What can we say about a relative size of CP-even and CP-odd Higgs boson couplings to heavy quarks at the LHC?

摘要

The determination of Higgs boson CP properties in associated production with heavy quark pair in hadron colliders was studied. It was found that using the full phase space dependence at the LHC in the process pp → t(t-bar)h should allow for distinguishing between different CP scenarios in both γγ and b(b-bar) Higgs boson decay modes.
