Abstract

Main parameters of Super proton-proton Collider (SppC) based lepton-proton colliders are estimated. For electron beam parameters, highest energy International Linear Collider (ILC) and Plasma Wake Field Accelerator-Linear Collider (PWFA-LC) options are taken into account. For muon beams, 1.5 TeV and 3 TeV center of mass energy muon collider parameters are used. In addition, ultimate μp collider which assumes construction of additional 50 TeV muon ring in the SppC tunnel is considered. It is shown that luminosity values exceeding 1032 cm-2 s-1 can be achieved with moderate upgrade of the SppC proton beam parameters. Physics search potential of proposed lepton-proton colliders is illustrated by considering small Björken x region as an example of SM physics and resonant production of color octet leptons as an example of BSM physics.

In order to evaluate physics search potential of the Super proton-proton Collider (SppC) based lp colliders we consider two phenomena; namely, small Bjorken x region is considered as an example of the SM physics and resonant production of color octet electron and muon is considered as an example of the BSM physics

Summary

Introduction

It is known that lepton-hadron scattering had played crucial role in our understanding of deep inside of matter. Extending the kinematic region by two orders of magnitude both in high Q2 and small x, HERA (the first and still unique lepton-hadron collider) with √s = 0.32 TeV has shown its superiority compared to the fixed target experiments and provided parton distribution functions (PDF) for LHC and Tevatron experiments (for review of HERA results see [3, 4]). Construction of linear e+e−colliders (or dedicated linac) and muon colliders (or dedicated muon ring) tangential to the future circular pp colliders, FCC or SppC, as shown, will give opportunity to use highest energy proton beams in order to obtain highest center of mass energy in lepton-hadron and photon-hadron collisions (for earlier studies on linac-ring type ep, γp, eA, and γA colliders, see reviews [6, 7] and papers [8,9,10,11,12,13,14]).
