Medium-induced modification of Z -tagged chargedparticle yields in Pb+Pb collisions at 5 .
02 TeV with the ATLAS detector
The ATLAS Collaboration
The yield of charged particles opposite to a Z boson with large transverse momentum ( p T ) ismeasured in 260 pb − of pp and 1 . − of Pb+Pb collision data at 5 .
02 TeV per nucleon pairrecorded with the ATLAS detector at the Large Hadron Collider. The Z boson tag is usedto select hard-scattered partons with specific kinematics, and to observe how their showersare modified as they propagate through the quark–gluon plasma created in Pb+Pb collisions.Compared with pp collisions, charged-particle yields in Pb+Pb collisions show significantmodifications as a function of charged-particle p T in a way that depends on event centralityand Z boson p T . The data are compared with a variety of theoretical calculations and providenew information about the medium-induced energy loss of partons in a p T regime difficult tomeasure through other channels. © 2020 CERN for the benefit of the ATLAS Collaboration.Reproduction of this article or parts of it is allowed as specified in the CC-BY-4.0 license. a r X i v : . [ nu c l - e x ] A ug ollisions of heavy nuclei at ultrarelativistic energies at the Large Hadron Collider (LHC) and theRelativistic Heavy Ion Collider (RHIC) are understood to produce an extended region of hot and densematter where partons exist in a deconfined state known as the quark–gluon plasma (QGP). The highdensity of unscreened color charges in the QGP causes the showers of hard-scattered partons with largetransverse momentum ( p T ) to be modified as they traverse the medium [1]. These modifications areobserved in measurements of dijet and photon–jet momentum imbalance [2–5], and in jet fragmentationfunctions [6, 7].The large integrated luminosity of Pb+Pb collisions delivered during LHC Run 2 has enabled measurementsof jets produced in association with a high- p T Z boson. At leading order, the Z boson and the jet areproduced back-to-back in the azimuthal plane, with equal p T . Since Z bosons and their decay leptons, orsimilarly, photons, do not participate in the strong interaction and are not modified by the QGP [8, 9],they provide an estimate of the p T and azimuthal direction of the partner hard-scattered parton before thedeveloping shower is modified through interactions with the QGP [10, 11]. Measurements of photon-taggedfragmentation functions at the LHC [12, 13] and photon–hadron correlations at RHIC [14, 15] used thisfeature to perform detailed studies of jet quenching. At fixed p T , jets balancing Z bosons and photonsarise from processes with different Q , and can test the sensitivity of the energy loss process to partonvirtuality. Additionally, the use of isolated photons at low photon- p T ( (cid:46)
60 GeV) is difficult due to thelarge hadron-decay background, motivating the use of Z bosons. A measurement of Z +jet production with p Z T >
60 GeV by CMS demonstrates that the total p T carried inside the jet cone is decreased in Pb+Pbevents compared with that in pp events [16]. However, the modification of the jet’s constituent particle p T distributions, or any lower p Z T selections, have not yet been studied.This Letter presents a measurement of the yield of charged particles produced opposite in azimuth toa Z boson with p Z T >

02 TeV with the ATLAS detector at the LHC. The Pb+Pb and pp data were recorded in 2018and 2017, respectively, and correspond to integrated luminosities of up to 1 . − and 260 pb − . Thecharged particles are required to have p chT > Z bosonin the transverse plane , with azimuthal separation ∆ φ larger than 3 π /
4. In simulations of pp collisions,particles meeting these criteria reside primarily in the leading jet azimuthally opposite to the Z boson. Theper- Z yields of charged particles, N ch , are reported as a function of p chT , ( / N Z ) (cid:16) d N ch / dp chT d ∆ φ (cid:17) , in pp and Pb+Pb collisions. To quantify the modification resulting from the partons’ propagation through theQGP, the ratio of particle yields between Pb+Pb and pp collisions, I AA , is reported and compared withthe expectations from theoretical calculations. This measurement explores phenomena similar to those inmeasurements of the photon-tagged jet fragmentation function [12]. However, requiring a reconstructedjet may result in a bias towards events with less energy loss than average [17–19]. Since there is no suchrequirement in this measurement, it provides additional insight into energy loss in an unbiased way, at low p Z / γ T values which have not yet been measured at the LHC and where theoretical models have not beentested.The ATLAS experiment [20] is a multipurpose particle detector with a forward–backward symmetriccylindrical geometry and a near 4 π coverage in solid angle. It consists of an inner tracking detectorsurrounded by a superconducting solenoid providing a 2 T axial magnetic field, electromagnetic andhadron calorimeters, and a muon spectrometer. The inner tracking detector covers the pseudorapidity range 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. Cylindrical coordinates ( r , φ ) are used in the transverse plane, φ being the azimuthal anglearound the z -axis. The pseudorapidity is defined in terms of the polar angle θ as η = − ln tan ( θ / ) . η | < .
5. It consists of silicon pixel, silicon microstrip, and transition radiation tracking detectors [21,22]. Lead/liquid-argon (LAr) sampling calorimeters provide electromagnetic (EM) energy measurementswith high granularity. A steel/scintillator-tile hadron calorimeter covers the central pseudorapidity range( | η | < . | η | = .
2) and forward (FCal, up to | η | = .
9) regions. The muon spectrometer surroundsthe calorimeters and includes three air-core toroidal superconducting magnets with field integrals rangingbetween 2.0 and 6.0 T m, a system of precision tracking chambers, and fast detectors for triggering. DuringPb+Pb data-taking, the muon system was operational for only 1.4 nb − of the total integrated luminosity.Thus the dimuon channel is analyzed only in this subset of data.Events with a high- p T electron or muon are initially selected for analysis by the single-lepton triggersdescribed in Refs. [23, 24]. The centrality of Pb+Pb events is defined using the total transverse energymeasured in the FCal [4, 25], Σ E PbT . Pb+Pb events are divided into three categories which correspond tothe 0–10%, 10–30%, and 30–80% centrality intervals in minimum-bias (MB) events, the smaller valuesindicating larger nuclear overlap regions and thus larger, hotter QGP regions. The orientation of theunderlying event (UE) elliptic flow is determined from the azimuthal distribution of the FCal energy [26,27]. In pp events, the average number of interactions per bunch crossing ranged from 2 to 4, and thus allcharged-particle tracks are required to originate from the primary reconstructed vertex [28].Monte Carlo simulations of √ s = .
02 TeV pp collisions with Z bosons decaying in the dielectron anddimuon channels, as well as data-driven studies, are used to correct the data for bin migration andreconstruction inefficiencies. Generated events were passed through a Geant4 simulation [29, 30] of theATLAS detector under the same conditions present during data-taking and were digitized and reconstructedin the same way as the data. The Z boson events were generated at next-to-leading order (NLO) with thePowheg-Box v2 program [31–34] interfaced to the Pythia 8.186 parton shower model [35]. The NLOCT10 parton distribution function (PDF) set [36] was used in the matrix element, while the CTEQ6L1PDF set [37] and the AZNLO tuned set of parameters [38] were used to model the parton shower.Four million events were generated to serve as the simulation sample for pp collisions. To model Pb+Pbevents, fifteen million simulated pp events were overlaid at the detector-hit level with MB Pb+Pb events indata. This data-overlay sample was reweighted on an event-by-event basis to match the Σ E PbT distributionfor Pb+Pb events containing Z bosons.The Z bosons in pp and Pb+Pb events are reconstructed in opposite-sign dielectron and dimuon decaychannels using procedures similar to those described in Refs. [9, 39]. Reconstructed electrons are requiredto have a transverse momentum p e T >
20 GeV, to lie within the fiducial acceptance of the EM barrel( (cid:12)(cid:12) η e (cid:12)(cid:12) < .
37) or endcap (1 . < (cid:12)(cid:12) η e (cid:12)(cid:12) < .
47) detectors, and to satisfy “loose” likelihood-based identificationcriteria, which have been optimized separately for pp and Pb+Pb events [40]. Reconstructed muons arerequired to have a transverse momentum p µ T >
20 GeV, to lie within the fiducial acceptance of the muonspectrometer ( (cid:12)(cid:12) η µ (cid:12)(cid:12) < . Z → (cid:96)(cid:96) candidates are required to be within the mass range 76 < m (cid:96)(cid:96) <
106 GeV and have p Z T >
15 GeV.This selection ensures that the contribution from multijet and other backgrounds is smaller than 1.5%(0.1%) for the dielectron (dimuon) channel, and is considered negligible. In total, these criteria selectapproximately 21 000 (28 000) Z → ee ( Z → µµ ) events in pp data, and 3400 (4100) events in Pb+Pbdata.Each Z data event is assigned a series of weights, derived from simulation and data, to account for thetrigger, reconstruction and selection efficiencies of its decay leptons. Individual lepton trigger efficienciesare determined directly in pp and Pb+Pb data using tag-and-probe techniques [23, 24], and are 0.70–0.803or each muon and 0.75–0.95 for each electron. Reconstruction and selection efficiencies are determinedusing simulation and are 0.65–0.80 for muons and 0.65–0.95 for electrons. Although the efficiencies mayvary substantially with the individual lepton p T , η and φ , the resulting dependence on p Z T is weak due tothe large Z mass and weak correlation between bosons and their decay leptons.Charged-particle tracks are reconstructed from hits in the inner detector using an algorithm [42] which,in Pb+Pb collisions, is optimized for the high-occupancy conditions [43]. They are required to meetseveral criteria intended to select primary charged particles [6]. All reconstructed tracks with p T > | η | < . ∆ φ > π / p chT resolution isfound to have a negligible effect ( (cid:46) . Z event in data, 40–160 unique MB events witha matching centrality are used for this estimation. Furthermore, to match any azimuthal modulation of theUE, the elliptic flow angles [27] in the Z data event and in the matching MB event must match within π / p chT , p Z T , and Pb+Pb centrality, with a minimum of5 × − at the lowest p chT and p Z T values in the most central events. In pp events, the UE is known to havelarger activity in a Z event than in an ordinary MB pp collision [44, 45], necessitating a different procedure.Here, the UE is determined in events with 1 < p Z T <
12 GeV in the azimuthal region perpendicular to the Z boson to avoid the contribution from jet particles.The data are further corrected for bin migration resulting from the finite resolution in the p Z T measurement.This is evaluated by comparing the per- Z charged-particle yields, where the Z selection is made at thegenerator level, with those after reconstruction, and is typically a 2–3% correction.The primary sources of systematic uncertainty in the yield measurement are those affecting the Z bosonreconstruction, those affecting the charged-particle selection, and those affecting the UE backgroundestimation and subtraction. The uncertainties associated with the electron and muon energy scales areevaluated using a common set of uncertainties [41, 46], and are typically negligible ( (cid:46) p chT . Those associated with lepton trigger and selection efficiency determination are smaller than theones related to the energy scale. Several sources of tracking-related uncertainty are considered, which aredescribed in previous measurements of charged-particle fragmentation functions [6, 47]. Of these, thelargest uncertainty is the sensitivity to the track selection criteria, which is 2–3%.The uncertainty in the determination of the UE background yield is evaluated by propagating the statisticaluncertainty of the UE estimation in MB events. The sensitivity of the UE estimation to the matching criteriafor the elliptic or triangular flow [26] angles between signal and MB events is investigated. However, sincethese variations give statistically compatible results, they are not included. As a check of the backgroundsubtraction procedure, the full analysis is performed on simulated Z events overlaid with Hijing [48]Pb+Pb background, and compared with the generator-level distributions. An absolute uncertainty in thebackground estimation of 0 .
3% is derived using this study.Finally, an internal consistency check is performed by comparing the per- Z yields between the electron andmuon decay channels. In p Z T and centrality selections where a difference is observed, an uncertainty of upto 4% in pp and up to 14% in Pb+Pb is included. 4or the yields at low p chT and in central events, the uncertainty from the UE determination is dominantand can be as large as 30%. For yields at high p chT and in lower-multiplicity events, the uncertaintiesassociated with the tracking efficiency are typically dominant, and as large as 5%. In all cases, the statisticaluncertainty is larger than the total systematic uncertainty.Figure 1 presents the charged-particle yield per Z boson, in Pb+Pb and pp events, as a function of p chT .The yields in Pb+Pb collisions are observed to be modified relative to those in pp collisions. To betterreveal the modification, Figure 2 presents I AA values, the ratios of yields in Pb+Pb events to those in pp events. The I AA values are suppressed below unity at large p chT , with a systematically larger suppressionin more central events and for lower p Z T selections. At low p chT , less than 2–3 GeV, the I AA values aretypically greater than unity, although the uncertainties limit the precision with which this enhancementcan be measured. The suppression over a wide range of p chT values, and the general enhancement of the I AA above unity at lower p chT , are qualitatively similar to those observed in the ratios of jet fragmentationfunctions in photon-tagged events [12].Figure 3 compares the I AA in 0–10% Pb+Pb events with the following theoretical calculations, whereavailable, which use the same kinematic selections as the data: (1) a perturbative calculation within theframework of soft-collinear effective field theory with Glauber gluons (SCET G ) in the soft-gluon-emission(energy-loss) limit, with jet-medium coupling g = . ± . p chT , greater than 10 GeV. The Hybrid model,JEWEL and CoLBT qualitatively capture the increase at low p chT . Several of these models also capture therelative difference in the I AA between the three p Z T selections. A full evaluation of theoretical uncertaintiesis needed to further discriminate between the mechanisms of energy loss and medium response in thedata. 5 [GeV] chT p - -

In conclusion, this Letter presents a measurement of charged-particle yields produced in the azimuthaldirection opposite to a Z boson with p T >
15 GeV. The measurement is performed using 260 pb − of pp and up to 1 . − of Pb+Pb collision data at 5 .
02 TeV with the ATLAS detector at the Large HadronCollider. The per- Z yields are systematically modified in Pb+Pb collisions compared with pp collisions dueto the interactions between the parton shower and the hot and dense QGP medium. The charged-particle p T distribution in Pb+Pb collisions is softer than that in pp collisions, with a suppression at high p chT andan enhancement at low p chT . The degree of modification varies with Pb+Pb event centrality, consistentwith a larger and hotter QGP being created in more central events. At high p Z T , the modification patternis qualitatively similar to that observed in measurements of photon-tagged jet fragmentation functions.In addition to the particular theoretical comparisons presented here, the data will allow systematic testsof models across centrality and p Z T selections, including tests of energy loss for low- p T partons that areotherwise difficult to access experimentally.
