Enhanced $thj$ signal at the LHC with $h\to \gamma \gamma$ decay and $\mathcal{C}\mathcal{P}$-violating top-Higgs coupling

Jason Yue

We study the observability of non-standard top Yukawa couplings in the $pp\to t(\to \ell {\nu }_{\ell }b)h(\to \gamma \gamma )j$ channel at 14 TeV high-luminosity LHC (HL-LH…
