Search for top quark decays $t\to qH$, with $H\to \gamma \gamma$, in $\sqrt{s}=13$ TeV $pp$ collisions using the ATLAS detector

ATLAS Collaboration

This article presents a search for flavour-changing neutral currents in the decay of a top quark into an up-type ($q=c,u$) quark and a Higgs boson, where the Higgs boson decays…
