Abstract

Experimental searches on composite particles are performed using LHC proton–proton collision by the ATLAS and CMS collaborations. The composite particles considered in this article are vector-like quark/lepton, Z’ and W’. The results of the searches are presented using Run 2 data corresponding to luminosity between 36 and 139 \(\hbox {fb}^{-1}\) of the LHC collisions recorded at a center of mass of energy of 13 TeV. The analysis methodology used by each experiment is briefly described and compared.
