Prospect of the search for $${\mathrm {W}}^{\prime }$$ in vector boson fusion at the high-luminosity large hadron collider

Abstract

A search for a new heavy charged gauge boson $${\mathrm {W}}^{\prime }$$ produced via a vector boson fusion process with two hard jets in pp collisions in the high-luminosity Large hadron collider (HL-LHC) environment is presented. The HL-LHC will increase the peak instantaneous luminosity to $$7.5 \times 10^{34}~{\mathrm {cm}}^{-2}~{\mathrm {s}}^{-1}$$ and the center of mass energy of 14 TeV to collect integrated luminosities up to 3 $${\mathrm {ab}}^{-1}$$ , which will significantly improve sensitivity for the observation of new heavy particles via rare processes. In this paper, to investigate the signal sensitivity for a $${\mathrm {W}}^{\prime }$$ we use the heavy vector triplet model, in the context of a simplified phenomenological approach, under Monte-Carlo simulations. The search targets events with one energetic electron and large missing transverse momentum, as well as two jets with a large separation in pseudorapidity. The expected upper limit for the mass of $${\mathrm {W}}^{\prime }$$ and exclusion limit contour on coupling parameters are presented at the 95% confidence level for an integrated luminosity of 3 $${\mathrm {ab}}^{-1}$$ .
