Constraining certain Higgs couplings at the HL-LHC and beyond.
ABSTRACT :
In this talk, I will review the present status of the Higgs boson's properties since its discovery in 2012. I will focus on the measurements of several Higgs couplings, upon considering standard decay modes, in the context of an effective field theory. I will also discuss the possibility of strongly constraining the couplings affecting the triple gauge boson vertices upon studying the ZH channel in the boosted Higgs regime. I will show the potential of the High luminosity run of the LHC (HL-LHC) and the future 100 TeV FCC-hh machine, to constrain such couplings to stronger degrees than LEP had constrained earlier. Finally, I will discuss various studies pertaining to the measurement of the Higgs trilinear coupling at the HL-LHC and at a future 100 TeV collider.
