Top polarisation as a probe of CP-mixing top-Higgs coupling in $tjh$ signals

Riley Patrick, Andre Scaffidi, Pankaj Sharma

In this letter we explore beyond the Standard Model top-Higgs Yukawa couplings as a function of a CP-mixing parameter ${\xi }_t$ at the 14 TeV HL-LHC in the process $pp\to thj$. We obse…
