Projections for neutral Di-Boson and Di-Higgs interactions at FCC-he collider

Abstract

As a high energy e-p collider, FCC-he, has been recently proposed with sufficient energy options to investigate Higgs couplings. To analyze the sensitivity on Higgs boson couplings, we focus specifically on the CP-even and CP-odd Wilson coefficients with hhZZ and hh gamma gamma four-point interactions of Higgs boson with Effective Lagrangian Model through the process e(-)p -> hhje(-). We simulate the related processes in FCC-he, with 60 GeV and 120 GeV e(-) beams and 50 TeV proton beam collisions. We present the exclusion limits on these couplings both for 68% and 95% C.L. in terms of integrated luminosities. (C) 2018 The Author(s). Published by Elsevier B.V.
