Probing underlying event in Z-boson events using event shape observables

Abstract

Experimental measurements of observables sensitive to the underlying event (UE) in $Z$-boson events have been performed by both ATLAS and CMS experiments at the LHC. However, in the busy LHC environment, these observables receive substantial contribution from jets originating from initial state radiation (ISR). We probe if using event shape observables in conjunction with the UE observables can help us to disentangle the effect of the UE from jets originating in ISR.
