Description

The Large Hadron-Electron Collider (LHeC) will operate at √s = 1.2 TeV and accumulate about 1/ab of integrated electron-proton luminosity [1]. We report here results of a novel study of high energy photon-photon interactions at the LHeC, at the 𝛾𝛾 center-of-mass energy of up to 1 TeV, opening new frontiers in the electroweak physics. Despite very high ep luminosity, the experimental conditions will be very favorable at the LHeC – a negligible event pileup will allow for unique studies of exclusive production via two-photon fusion. We discuss a number of such processes, as 𝛾𝛾 → WW for example, including estimates of their principal backgrounds. We conclude by evaluating the impact of measurements at the LHeC of such two-photon interactions on testing of the electroweak sector of Standard Model and searches for physics beyond the SM.
