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

摘要

Highlights?The single Higgs photoproduction is studied at the LHC and at future linear collider.?The new physics is probed via a model independent analysis.?The sensitivity bounds on non-standard Higgs couplings are obtained with 95% CL.?We compare the results obtained from LHC and future linear collider.AbstractWe investigate the potential of single Higgs boson photoproduction at the LHC and ateγmode of future lineare?e+collider to probe non-standardHZγandHγγcouplings. We consider the semi-elastic production processpp?→?pγp?→?pHqXat the LHC whereqrepresents the quarks andXrepresents the remnants of one of the initial protons. We also study the single Higgs production throughγe?→?Hein theeγcollision 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.]]>
