Enhanced thj signal at the LHC with h→γγ decay and CP-violating top–Higgs coupling
We study the observability of non-standard top Yukawa couplings in the pp→t(→ℓνℓb)h(→γγ)j channel at 14 TeV high-luminosity LHC (HL-LHC). The small diphoton branching ratio is enhanced when the CP-violating phase, ξ, of the top–Higgs interaction is non-zero. When the modulus of the top–Higgs interac...
