Examining Nonstandard Higgs Couplings via Photon-Photon Fusion at FCC

Abstract

In this paper, the constraints on the non-standard HZ and H couplings through the exclusive single Higgs production process pp pp pHp at a future 100 TeV proton-proton collider have been examined. As the signal, H and HZ decay channels of the Higgs boson have been considered. Taking into account three different acceptance regions of 0.015<<0.15, 0.0015<  <0.5, 0<  <1- 𝑚�𝑝� 𝐸� and integrated luminosity of 𝐿�𝑖�𝑛�𝑡�= 3000 fb-1, it has been found 95% C.L. sensitivity constraints on these couplings. Similar calculations have been made at the LHC and discussed the improvement which is provided by a future 100 TeV proton-proton collider with respect to LHC.
