We evaluate the LHC discovery potential for a light Higgs boson in t tbar H (-> l nu b bbar b bbar jj) production, within the Standard Model and if a new Q=2/3 quark singlet T with a moderate mass exists. In the latter case, T pair…

In light of the recent discovery of a neutral Higgs boson, $H_{\rm obs}$, with a mass near 125 GeV, we reassess the LHC discovery potential of a charged Higgs boson, $H^\pm$, in the $W^\pm H_{\rm obs}$ decay channel. This decay channel can…
