Future circular collider based lepton–hadron and photon–hadron colliders: Luminosity and physics

Abstract Construction of future electron–positron colliders (or dedicated electron linac) and muon colliders (or dedicated muon ring) tangential to Future Circular Collider (FCC) will give opportunity to utilize highest energy proton and nucleus beams for lepton–hadron and photon–hadron collisions. Luminosity values of FCC based e p , μ p , e A , μ A , γ p and γ A colliders are estimated. Multi-TeV center of mass energy e p colliders based on the FCC and linear colliders (LC) are considered in detail. Parameters of upgraded versions of the FCC proton beam are determined to optimize luminosity of electron–proton collisions keeping beam–beam effects in mind. Numerical calculations are performed using a currently being developed collision point simulator. It is shown that L e p ∼ 1 0 32 cm − 2 s − 1 can be achieved with LHeC-like upgrade of the FCC parameters. Moreover, “dynamic focusing” scheme could provide opportunity to handle L e p ≳ 1 0 33 cm − 2 s − 1 .

Color octet electron search potential of FCC based e–p colliders

Resonant production of color octet electrons, e 8, at the FCC based e–p colliders is analyzed. It is shown that e-FCC will cover much a wider region of e 8 masses compared to the LHC. Moreover, with the highest electron beam energy, the e 8 search potential of the e-FCC exceeds that of the FCC p–p collider. If e 8 is discovered earlier by the FCC p–p collider, e-FCC will give an opportunity to handle very important additional information. For example, the compositeness scale can be probed up to the hundreds of TeV region.

A Provisional Study of ADS Within the Turkic Accelerator Complex Project

The Turkic Accelerator Complex (TAC) project has been developed with the support of the Turkish State Planning Organization by the collaboration of 10 Turkish universities. The complex is planned to have four main facilities, namely: SASE FEL Facility Based on 1 GeV Electron Linac, Third Generation Synchrotron Radiation Facility (SR) Based on 3.56 GeV Positron Synchrotron, Super-Charm Factory (

GeV) by colliding the electron beam coming from the linac with an energy of 1 GeV and positron beam coming through the positron ring with an energy of 3.56 GeV, GeV scale proton accelerator. Later has two-fold goal: Neutron Spallation Source (NSS) and ADS. The proton accelerator construction will have 3 MeV, 100 MeV, and 1 GeV phases. The technical design report is planned to be finished in 2013. Since Turkey has essential Thorium reserves the ADS becomes very attractive for our country as emerging energy technology.

Resonant production of color octet muons at Future Circular Collider-based muon-proton colliders

IceCube collaboration has published two papers on ultrahigh energy neutrinos observation, recently. They have used the data collected in two years in their first publication, which reveals observation of two PeV energy neutrino events. The second publication of the collaboration including more data has also confirmed main features of the former paper. In literature, various interpretations of the IceCube data have been proposed. In this study, it is shown that PeV energy neutrino events observed by the IceCube collaboration can be interpreted as resonance production of color octet neutrinos with masses in

Color octet neutrino as the source of the IceCube PeV energy neutrino events

OBJECTIVE To describe a lingual arch bar technique for fixation of rostral mandibular body fractures and report outcome in 16 cats. STUDY DESIGN Original study. ANIMALS Cats (n=16) with rostral mandibular body fracture (10 bilateral, 6 unilateral) just caudal to the canine teeth. METHODS Orthodontic wire (Dentaurum® ; 0.9 mm) was used as a lingual arch bar by contouring it to the shape of the lingual side of the alveolar margin, and secured by circum-mandibular wires passed interproximal to teeth. Stability of fixation, occlusion, tolerance to the lingual arch bar, degree of secondary gingivitis/periodontitis, and ability to eat were evaluated clinically, and fracture union was assessed radiographically. RESULTS The lingual arch bar was well tolerated. Eleven cats without a feeding tube were able to eat within 24 hours. Time to fracture union and appliance removal ranged from 28 to 64 days (mean, 42.5 days). Malocclusion of the rostral part of the fracture occurred in 5 cats; however only 1 required correction. CONCLUSIONS Intraoral stabilization of rostral mandibular fractures using a lingual arch bar is a simple and effective method for the treatment of rostral mandibular fractures just caudal to the canine teeth.

Resonant production of leptogluons at the FCC based lepton-hadron colliders

We investigate the resonant production of color octet muons in order to explore the discovery potential of the FCC-based \mu p colliders. It is shown that search potential of \mu p colliders essentially surpass potential of the LHC and would exceed that of FCC pp collider.
