Beyond Standard Model Hadron-Hadron Scattering Top Physics |
| description |
A search for the electroweak production of a vector-like quark T’, decaying to a top quark and a Higgs boson is presented. The search is based on a sample of proton-proton collision events recorded at the LHC at √s = 13 TeV, corresponding to an integrated luminosity of 138 fb−¹. This is the first T’ search that exploits the Higgs boson decay to a pair of photons. For narrow isospin singlet T’ states with masses up to 1.1TeV, the excellent diphoton invariant mass resolution of 1–2% results in an increased sensitivity compared to previous searches based on the same production mechanism. The electroweak production of a T’ quark with mass up to 960 GeV is excluded at 95% confidence level, assuming a coupling strength κT = 0.25 and a relative decay width Γ/MT’ < 5%. |
