Description
A search for flavour-changing neutral-current interactions involving the top quark, the Higgs boson and an up-type quark (q = u,c) with the ATLAS detector at the Large Hadron Collider is presented. The analysis considers leptonic decays of the top quark along with Higgs-boson decays into two W bosons, two Z bosons or a τ+τ− pair. It focuses on final states containing either two leptons (electrons or muons) of the same charge or three leptons, of which exactly two have an identical charge. The considered processes are tt_bar production with one top quark decaying via t → Hq and pp → Ht production. The proton-proton collision data set analysed amounts to 140 fb−1 at √s = 13 TeV.
