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

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 ep, mu p, eA, mu A, gamma p and gamma A colliders are estimated. Multi-TeV center of mass energy.... 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-ep greater than or similar to 10(33) 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-ep greater than or similar to 10(33) cm(-2) s(-1). (C) 2017 Elsevier B.V. All rights reserved.
