LHeC and eRHIC
نویسنده
چکیده
This paper is focused on possible designs and predicted performances of two proposed highenergy, high-luminosity electron-hadron colliders: eRHIC at Brookhaven National Laboratory (BNL, Upton, NY, USA) and LHeC at Organisation Européenne pour la Recherche Nucléaire (CERN, Geneve, Switzerland). The Relativistic Heavy Ion Collider (RHIC, BNL) and the Large Hadron Collider (LHC, CERN) are designed as versatile colliders. RHIC is colliding various species of hadrons staring from polarized protons to un-polarized heavy ions (such as fully stripped Au (gold) ions) in various combinations: polarized p-p, d-Au, Cu-Cu, Au-Au. Maximum energy in RHIC is 250 GeV (per beam) for polarized protons and 100 GeV/n for heavy ions. There is planed expansion of the variety of species to include polarized He and unpolarized fully stripped U (uranium). LHeC is designed to collide both un-polarized protons with energy up to 7 TeV per beam and fully stripped Pb (lead) ions with energy up to 3 TeV/n.

Parton distributions and small-x QCD at the Large Hadron Electron Collider
The proposed Large Hadron Electron Collider (LHeC) at CERN would bring DeepInelastic scattering into the unexplored TeV regime. The LHeC rich physics program, among other topics, includes both precision SM measurements to complement LHC physics as well as studies of QCD in the high energy limit. The present contribution reports on ongoing studies within the NNPDF framework towards the LHeC CDR....
متن کاملProbing Anomalous WW γ and WWZ Couplings with Polarized Electron Beam at the LHeC and FCC-Ep Collider
Abstract—We study the anomalous WW and WWZ couplings by calculating total cross sections of two processes at the LHeC with electron beam energy Ee=140 GeV and the proton beam energy Ep=7 TeV, and at the FCC-ep collider with the polarized electron beam energy Ee=80 GeV and the proton beam energy Ep=50 TeV. At the LHeC with electron beam polarization, we obtain the results for the difference of ...
متن کاملParton Distributions at the LHeC
The LHeC provides e±p collisions at 1.4 TeV cms energy. Based on simulations of the statistics and the systematics as may be achieved with a new collider detector, the potential of the LHeC is characterised regarding DIS precision measurements as of the strong coupling constant, to per mille accuracy, and the gluon distribution. It is demonstrated that for the first time the flavour contents of...
متن کاملPOTENTIAL USE OF eRHIC’s ERL FOR FELS AND LIGHT SOURCES
One of the designs of a future electron-hadron collider, eRHIC, is based on a 5-10 GeV high current energy-recovery linac (ERL) with possible extension of its energy to 20 GeV. This ERL will operate with high brightness electron beams, which naturally match requirements for X-ray FELs and other next generation light sources. In this paper we discuss possible scenarios of using the eRHIC ERL in ...
متن کاملFINAL-FOCUS OPTICS FOR THE LHeC ELECTRON BEAM LINE∗
One of the options considered for the ECFA-CERNNuPECC design study for a Large Hadron electron Collider (LHeC) [1] based on the LHC is adding a recirculating energy-recovery linac tangential to the LHC. First designs of the electron Final Focus System have shown the need to correct the chromatic aberrations. Two designs using different approaches for the chromaticity correction are compared, na...
