A complete next-to-leading order QCD description of resonant $Z^{\prime }$ production and decay into $t\bar{t}$ final states

Fabrizio Caola, Kirill Melnikov, Markus Schulze

We discuss QCD radiative corrections to the production of a heavy neutral resonance $Z^{\prime }$ at the LHC assuming that it decays into a $t\bar{t}$ final state. Compared to previous stud…
