Experimental Results on Multiple Heavy Vector Boson Production at the LHC

Abstract

Multiple heavy vector boson production in $pp$ collisions at the LHC is a good testing ground for new physics. The simplest way to obtain four such bosons, namely $W^{+}W^{-}W^{+}W^{-}$, in the final state is to have two $tt^{-}$ pairs in a single event. Three heavy vector bosons can be produced in events with two pairs of top quarks, with one $tt^{-}$-pair and additional top quark, with one $tt^{-}$-pair plus a heavy boson, with one top quark plus two vector bosons as well as directly. This paper summarizes results on the mentioned multiple heavy vector boson production by the ATLAS and CMS experiments at the Large Hadron Collider. They are mostly based on datasets accumulated at $\sqrt{s}=13$ TeV during the whole Run2.
