Non-standard Higgs couplings in single Higgs boson production at the LHC and future linear collider

Abstract

We investigate the potential of single Higgs boson photoproduction at the LHC and at eγ mode of future linear e−e+ collider to probe non-standard HZγ and Hγγ couplings. We consider the semi-elastic production process pp → pγp → pHqX at the LHC where q represents the quarks and X represents the remnants of one of the initial protons. We also study the single Higgs production through γe → He in the eγ collision at the future linear collider. We perform a model-independent analysis and obtain the sensitivity bounds on the non-standard Higgs couplings for both colliders. We compare the capability of single Higgs photoproduction process at these two colliders to probe non-standard Higgs couplings.
