Talk 01. Higgs Physics

### Speaker

Prof. Chung Kao (University of Oklahoma)

### Description

We investigate the prospects for discovering a top quark decaying into
one light Higgs boson ($h^0$) along with a charm quark
in top quark pair production at the CERN Large Hadron Collider (LHC)
A general two Higgs doublet model is adopted to study the signature
of flavor changing neutral Higgs (FCNH) interactions with $t \to c h^0$,
followed by $h^0 \to \tau^+ \tau^-$.
We study the discovery potential for the FCNH signal and physics background
from dominant processes with realistic acceptance cuts
and tagging efficiencies.
Promising results are found for the LHC running at 13 or 14 TeV
collision energy as well as a future pp collider at 27 TeV.
