Title: Probing Higgs boson CP Properties with ttH at the LHC and the 100 TeV pp collider
Abstract:
The Higgs boson H has the largest coupling to the top quark
t among the standard model (SM) fermions. This is one of the ideal places to
investigate new physics beyond SM. In this work, we study the potential of
determining Higgs boson CP properties at the LHC and future 33 TeV and 100 TeV
pp colliders by analysing various operators formed from final states variables
in ttH production. The discrimination power from SM coupling is obtained with
Higgs boson reconstructed from H → γγ and H → bb. We find that ttb¯b process can
provide more than 3σ discrimination power with 300 /fb integrated luminosity in
a wide range of allowed Higgs to top couplings for the LHC, the 33 TeV and 100
TeV colliders. For ttγγ the discrimination power will be below 3σ at the LHC,
while for 33 TeV and 100 TeV colliders, more than 3σ sensitivity can be
reached.
