 Search for flavor-changing neutral currents in top quark decays $t\to Hc$ and $t \to Hu$ in multilepton final states in proton--proton collisions at $\sqrt{s}= 13$ TeV with the ATLAS detector / ATLAS Collaboration Flavor-changing neutral currents are not present in the Standard Model at tree level and are suppressed in loop processes by the unitarity of the Cabibbo--Kobayashi--Maskawa matrix; the corresponding rates for top quark decay processes are experimentally unobservable.
