Constraining four-fermion operators using rare top decays

Abstract New physics can manifest itself by an appreciable increase of the decay rate of top quarks in rare flavour-changing final states. Exploiting the large top quark production rate at the LHC, we bound four-fermion operators contributing to non-resonant t → ℓ + ℓ − j using different signal regi...
