Search for charged-lepton flavour violation in top quark interactions with an up-type quark, a muon, and a $\tau$ lepton in proton-proton collisions at $\sqrt{s}$ = 13 TeV

CMS Collaboration

A search for charged-lepton flavour violation (CLFV) in top quark (t) production and decay is presented. The search uses proton-proton collision data corresponding to 138 fb${}^{-1}$…
