Probing new physics in top decays

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 using
different signal regions of the latest LHC searches for $t \to Zj$. We also
provide prospects for the high-luminosity LHC to test these as well as four-fermion
operators contributing to $t \to bbj$, based on improved analysis strategies of
existing searches. Finally, we discuss rare top decays within extended
effective-field theories.
