Abstract

This study examines the production of dark matter events in association with a Z′ boson decaying via leptonic channels in simulated proton–proton collisions at the Large Hadron Collider. The analysis focuses on collisions at a center-of-mass energy of s=14TeV under high-luminosity conditions, corresponding to an integrated luminosity of 1000fb−1. Using Monte Carlo simulations interpreted within the Effective Field Theory (EFT) framework, this work investigates potential signatures of new physics. In the absence of such signals, upper limits are set on key EFT parameters, including the theory's cutoff scale and the mass of the Z′ boson.
