${\mathbf{Z}}^{\prime }$-boson dilepton searches and the high-$\mathbf{x}$ quark density

Abstract

We study the influence of theoretical systematic uncertainties due to the quark density on LHC experimental searches for $Z^{\prime }$-bosons. Using an approach originally proposed in the context of the ABMP16 PDF set for the high-$x$ behaviour of the quark density, we presents results on observables commonly used to study $Z^{\prime }$ signals in dilepton channels.
