Longitudinal flow decorrelations in Xe + Xecollisions at √ s NN = .
44 TeV with the ATLAS detector
The ATLAS Collaboration
The first measurement of longitudinal decorrelations of harmonic flow amplitudes v n for n =
2, 3 and 4 in Xe + Xe collisions at √ s NN = .
44 TeV is obtained using 3 µ b − of datawith the ATLAS detector at the LHC. The decorrelation signal for v and v is found to benearly independent of collision centrality and transverse momentum ( p T ) requirements onfinal-state particles, but for v a strong centrality and p T dependence is seen. When comparedwith the results from Pb + Pb collisions at √ s NN = .
02 TeV, the longitudinal decorrelationsignal in mid-central Xe + Xe collisions is found to be larger for v , but smaller for v . Currenthydrodynamic models reproduce the ratios of the v n measured in Xe + Xe collisions to those inPb + Pb collisions but fail to describe the magnitudes and trends of the ratios of longitudinalflow decorrelations between Xe + Xe and Pb + Pb. These results provide new insights into thelongitudinal structure of the initial-state geometry in heavy-ion collisions. c (cid:13) a r X i v : . [ nu c l - e x ] J a n igh-energy heavy-ion collisions create a new state of matter known as a quark–gluon plasma (QGP),whose space-time dynamics is well described by relativistic viscous hydrodynamic models [1–3]. Duringits expansion, the large pressure gradients of the QGP convert the spatial anisotropies in the initial-state geometry into momentum anisotropies of the final-state particles. Such momentum anisotropiesare often characterized by a Fourier expansion of particle density in the azimuthal angle φ , dN / d φ ∝ + (cid:80) ∞ n = v n cos n ( φ − Φ n ), where v n and Φ n are the magnitude and phase of the n th -order anisotropy.Extensive studies of v n and their event-by-event fluctuations in the last decade [4–14] have providedstrong constraints on the properties of the QGP and the initial-state geometry [15–20]. Most of thesestudies, however, assume that the initial condition and dynamic evolution of the QGP are boost-invariantin the longitudinal direction. Recently, LHC experiments made the first observation [21, 22] of “flowdecorrelations” in Pb + Pb collisions, which show that, even in a given event, v n and Φ n can fluctuate alongthe longitudinal direction. Hydrodynamic model calculations [23–28] show that such flow decorrelationsare driven mostly by primordial longitudinal structure in the initial-state geometry. Testing how flowdecorrelations vary with the size of the collision system can improve our knowledge about the early-timedynamics of the QGP.This Letter investigates the system-size dependence of longitudinal decorrelations of v , v , v by perform-ing measurements in Xe + Xe collisions and comparing them with Pb + Pb collisions. Recentmeasurements [29–31] show that the v n exhibit modest di ff erences ( < ff erence for v is significantlylarger. Model calculations [32, 33] suggest that these di ff erences are compatible with the expected orderingof the initial eccentricities and roles of viscous e ff ects in the two systems. It is of great interest to studywhether the relative strength of the v n decorrelation between the two systems follows that of the inclusive v n , which should provide insight into the nature of the initial sources responsible for both the transverseharmonic flow and its longitudinal fluctuations.The measurement is performed using the ATLAS inner detector (ID) and forward calorimeters (FCal)along with the trigger and data acquisition system [34, 35]. The ID measures charged particles overa pseudorapidity range | η | < . (cid:80) E T over 3 . < | η | < . ∆ η × ∆ φ of approximately 0 . × .
1. TheATLAS trigger system [35] consists of a level-1 (L1) trigger implemented using a combination of dedicatedelectronics and programmable logic, and a software based high-level trigger.This analysis uses 3 µ b − of √ s NN = .

9, as estimated in the L1trigger system, to be larger than 4 GeV. In the o ffl ine analysis, the z -position of the primary vertex [39] ofeach event is required to be within 100 mm of the nominal IP. Events containing more than one inelasticinteraction (pileup) are suppressed by exploiting the correlation between the (cid:80) E T measured in the FCaland the number of tracks associated with a primary vertex. The fraction of pileup after event selection isestimated to be less than 0.2%. The event centrality classification is based on the (cid:80) E T in the FCal [40].A Glauber model [41, 42] is used to determine the mapping between (cid:80) E T in the FCal and the centrality ATLAS uses a right-handed coordinate system with its origin at the nominal interaction point (IP) in the center of the detectorand the z -axis along the beam pipe. The x -axis points from the IP to the center of the LHC ring, and the y -axis pointsupward. Cylindrical coordinates ( r , φ ) are used in the transverse plane, φ being the azimuthal angle around the beam pipe. Thepseudorapidity is defined in terms of the polar angle θ as η = − ln tan( θ/ N part , foreach centrality interval. This analysis is restricted to the 0–70% centrality percentiles where the L1 triggeris estimated to be fully e ffi cient.Charged-particle tracks are reconstructed from ionization hits in the ID using a reconstruction proceduredeveloped for tracking in dense environments in proton–proton ( pp ) collisions, and optimized for heavy-ion collisions [43]. Tracks used in this analysis are required to have transverse momentum ( p T ) 0 . < p T < | η | < .
4, at least two pixel hits, a hit in the first pixel layer when one is expected, at least eightSCT hits, and no missing hit in the SCT. In addition, the point of closest approach of the track is requiredto be within 1 mm of the primary vertex in both the transverse and longitudinal directions. More details ofthe track selection can be found in Ref. [31]. The range of accepted track p T is chosen to be the same asused in the previous analysis [22] of Pb + Pb collisions.The e ffi ciency (cid:15) ( p T , η ) of the track reconstruction and track selection requirements is evaluated usingminimum-bias Xe + Xe Monte Carlo (MC) events produced with the HIJING [44] event generator withthe e ff ect of flow added using the procedure described in Ref. [45]. The response of the detector wassimulated [46] using G eant | η | <
1, the e ffi ciency is 60% at low p T and increases to 73% at higher p T . For | η | >
1, the e ffi ciency ranges between 40% and 60% depending on the p T . The e ffi ciency depends onlyweakly on the centrality; a change of about 3% over the full centrality range is observed for p T < (cid:15) ( p T , η ), which arises mainly from the uncertainty in the detector material budget, variesfrom 1% to 4% depending on p T and η . The rate of falsely reconstructed (fake) tracks f ( p T , η ) is found tobe significant only for p T < . η near zero to 6%for | η | >
2. The fake rate decreases rapidly for higher p T values.The method and analysis procedure closely follow those established in Ref. [22], and are described brieflybelow. The n th -order azimuthal anisotropy in an event is estimated using the observed flow vectors: q n ≡ Σ j w j e in φ j / ( Σ j w j ) (1)where the sum runs over charged particles (for the ID) or towers (for the FCal) in a specified η interval,and φ j and w j are the azimuthal angle and the weight assigned to each track or tower, respectively.The weight for the FCal is the E T of each tower, and the weight for the ID is calculated as d ( η, φ )(1 − f ( p T , η )) /(cid:15) ( p T , η ) [48] to correct for tracking performance. The additional factor d ( η, φ ), derived from thedata, corrects for azimuthal nonuniformity of the detector performance in each η interval. The flow vectors q n are further corrected by an event-averaged o ff set, q n − (cid:104) q n (cid:105) , to account for detector e ff ects.The longitudinal flow decorrelations are studied using products of flow vectors in the ID, q n ( η ) and in theFCal, q n ( η ref ) [21], averaged over events in a given centrality interval, r n | n ( η ) = (cid:104) q n ( − η ) q ∗ n ( η ref ) (cid:105)(cid:104) q n ( η ) q ∗ n ( η ref ) (cid:105) = (cid:104) v n ( − η ) v n ( η ref ) cos n [ Φ n ( − η ) − Φ n ( η ref )] (cid:105)(cid:104) v n ( η ) v n ( η ref ) cos n [ Φ n ( η ) − Φ n ( η ref )] (cid:105) , (2)where η ref is a reference pseudorapidity range in the FCal, common to both the numerator and thedenominator. The r n | n correlator defined this way quantifies the decorrelation between η and − η [21, 49].Three reference η ranges, 3 . < | η ref | < .
0, 4 . < | η ref | < . . < | η ref | < . (cid:10) q n ( − η ) q ∗ n ( η ref ) (cid:11) = (cid:10) q n ( η ) q ∗ n ( − η ref ) (cid:11) for a symmetric system, the correlator is further symmetrized toenhance the statistics, r n | n ( η ) = (cid:10) q n ( − η ) q ∗ n ( η ref ) + q n ( η ) q ∗ n ( − η ref ) (cid:11) (cid:104) q n ( η ) q ∗ n ( η ref ) + q n ( − η ) q ∗ n ( − η ref ) (cid:105) . ff erences between η and − η in thedetector performance.If flow harmonics for two-particle correlation from two di ff erent η factorize into single-particle harmonics,i.e. (cid:104) v n ( η ) v n ( η ) (cid:105) = (cid:68) v n ( η ) (cid:69) (cid:68) v n ( η ) (cid:69) , then it is expected that r n | n ( η ) =
1. Therefore, a value of r n | n ( η )incompatible with unity implies a factorization-breaking e ff ect due to longitudinal flow decorrelations.The deviation of r n | n from unity can be parameterized with a linear function, r n | n ( η ) = − F n η . The slopeparameter F n is obtained via a simple linear-regression [22], F n = (cid:80) i (1 − r n | n ( η i )) η i (cid:80) i η i , (3)where the sum runs over all r n | n data points as a function of η . If r n | n is a linear function in η , thelinear-regression is equivalent to a linear fit, but it is well defined even if r n | n has nonlinear behavior.Systematic uncertainties in r n | n and the slope parameter F n arise from the uncertainties in the reconstructionand track selection e ffi ciency, the acceptance reweighting procedure and the centrality definition. Most ofthese enter the analysis through the particle weights in Eq. (1). The systematic uncertainties are estimatedby varying di ff erent aspects of the analysis, recalculating r n | n and F n and comparing them with the nominalvalues. The systematic uncertainty associated with fake tracks is estimated by loosening the requirementson the transverse and longitudinal impact parameters [31]; the resulting changes are 1–2% for F , 1–4%for F , and 1–9% for F . The uncertainty associated with the e ffi ciency (cid:15) ( p T , η ) is evaluated by varyingthe tracking e ffi ciency up and down within its uncertainties; the influence is less than 1% for F n . The e ff ectof reweighting to account for nonuniformity in the detector azimuthal acceptance is studied by setting d ( η, φ ) = F and F , and 2–7% for F . The uncertainty due to the centrality definition is estimated by varying the mapping between (cid:80) E T and centrality percentiles; the influence is 0.5–4% for F and F , and 0.5–8% for F . In most of thecases, the total systematic uncertainties are smaller than the corresponding statistical uncertainties. Finally,HIJING events with azimuthal anisotropy imposed according to measured v n but without decorrelationsare used to cross-check the detector performance: the q n are calculated using both the generated andreconstructed tracks, and the resulting correlators are compared and found to be consistent within theirstatistical uncertainties.Figure 1 shows the measured r n | n ( η ) for n =
2, 3 and 4 in six centrality intervals, quantifying the flowdecorrelation between η and − η according to Eq. (2). The r n | n values show an approximately linear decreasewith η , implying stronger flow decorrelation at large η . The magnitudes of decorrelation for r | and r | are significantly larger than that for r | . The range 4 . < | η ref | < . r | is di ff erent from therange 3 . < | η ref | < . r | and r | in order to reduce sensitivity to nonflow correlations; this isfurther discussed below.The slope parameter F n is calculated from r n | n via Eq. (3) and summarized in Figure 2 as a function ofcentrality percentile. The left panels show the F n for three | η ref | ranges and right panels show the F n forthree p T ranges. Within uncertainties, F and F show very weak dependence on centrality. The F values,on the other hand, show a strong centrality dependence: they are smallest in the 20–30% centrality intervaland larger towards more-central or more-peripheral collisions. This strong centrality dependence is relatedto the fact that v is dominated by the average elliptic geometry in mid-central collisions and therefore isless a ff ected by decorrelations, while it is dominated by fluctuation-driven collision geometries in centraland peripheral collisions [25, 26]. 4 .5 1 1.5 2 h n | n r Centrality : 0-5%

The error bars and shaded boxes representstatistical and systematic uncertainties, respectively. Figure 2 also shows that F has sizable variation between various choices of | η ref | or p T in central andmid-central collisions. The contribution from nonflow correlations associated with back-to-back dijetscould bias the decorrelation signal [22, 50]. Since the gap between η and η ref in the denominator of r n | n is smaller than the gap between − η and η ref in the numerator, the nonflow contributions from dijets areexpected to contribute to the denominator more than the numerator and therefore tend to increase the F n values. Such nonflow contributions are expected to be larger for smaller | η ref | or larger p T . However,although the data show a larger F for smaller | η ref | compatible with nonflow, they show a smaller F forlarger p T , opposite to the expectation from nonflow contributions. Within uncertainties, the F and F , aswell as the original r | and r | , show no di ff erences between various p T or | η ref | ranges, suggesting thatthey are not a ff ected by nonflow. All these trends are qualitatively similar to the previous observations inPb + Pb collisions at √ s NN = .

02 TeV from Ref. [22] asa function of centrality percentile (left column) or N part (right column). Since F n depends only very weaklyon √ s NN [22], the 8% di ff erence in √ s NN between the two systems is expected to play negligible role forthis comparison. For both systems, F shows a strong dependence on centrality percentile and N part , while F and F each show rather weak dependence. In the noncentral collisions (centrality percentiles (cid:38) N part (cid:46) F for the two systems agree only as a function of N part , while F agree as a function ofeither centrality percentiles or N part . When compared as a function of centrality percentile, both F and F agree in the most central collisions, but they do not agree as a function of N part in the large N part region.

The F values have rather weak dependence on both centrality percentile and N part , andthey agree between the two systems. The data are also compared with results from a hydrodynamic modelwith longitudinal fluctuations included [51, 52]. This model describes quantitatively the behavior of F and F in mid-central collisions, but fails to describe the magnitude of F and the splitting between thetwo systems.To help further understand the relationship between the transverse harmonic flow and its longitudinalfluctuations, Figure 4 compares the ratios of flow decorrelation F XeXe n / F PbPb n ( F n -ratios) for 0 . < p T < v XeXe n /v PbPb n ( v n -ratios) for 0 . < p T < v n -ratios all decrease with centrality percentile, the F n -ratios6 entrality [%] F ATLAS < 3.0 GeV T ref h Xe+Xe, 4.0 < | | < 4.9 ref h Pb+Pb, 4.0 < |

Beyond thisoverall opposite trend, there are other contrasting features between the two types of ratios. The F -ratiois always above one, while the v -ratio decreases to below one around 10–20% centrality; the F -ratio islarger than the v -ratio except in the 0–5% centrality interval where the v -ratio is enhanced due to thedeformation of the Xe nucleus [32]. The di ff erences between the F -ratio and the v -ratio are smaller,but with di ff erent centrality dependencies: while the v -ratio decreases nearly linearly with centralitypercentile, the F -ratio first decreases and then increases as a function of centrality percentile. The F -ratiohas larger uncertainties, but shows much stronger centrality dependence compared with the v -ratio.

This comparison suggests that the longitudinal structure of theinitial geometry may have a di ff erent system-size dependence from its transverse structure.In summary, ATLAS presents the first measurement of longitudinal decorrelations for harmonic flowamplitudes v n in Xe + Xe collisions at √ s NN = .

3. This reverse ordering was not observed for theratios of v and v harmonic flows between the two collision systems. Hydrodynamic models are foundto describe the ratios of v n between Xe + Xe and Pb + Pb, but fail to describe most of the magnitudes andtrends of the ratios of the v n decorrelations between Xe + Xe and Pb + Pb. This suggests that models tuned todescribe the transverse dynamics may not necessarily describe the longitudinal structure of the initial-stategeometry. System-size dependence of flow decorrelations provides new insights into the dynamics of v n inthe longitudinal direction. This measurement provides important input for the complete modeling of thethree-dimensional initial conditions of heavy-ion collisions used in hydrodynamic models. Acknowledgements
