Investigating a new neutral heavy gauge boson within the mono-Z^ model via simulated pp collisions at s = 14 TeV at the HL-LHC

In this study, we aim to explore the potential for generating events related to dark matter (DM) in conjunction with a neutral heavy gauge boson (Z^) decaying leptonically during proton-proton collisions at the Large Hadron Collider (LHC). These collisions occur at a center-of-mass energy of 14 TeV, with a high integrated luminosity equivalent to 1000 fb^-1. Our analysis involves interpreting the outcomes through Monte Carlo simulation of the effective field theory (EFT) framework. If no new physics is detected, we establish constraints on various parameters within the EFT context, such as the scenario cutoff scale () and the Z^ mass.
