摘要

本研究考察了在大型强子对撞机模拟质子-质子碰撞中，与Z’玻色子通过轻子通道衰变相关的暗物质事件的产生。分析的重点是高光度条件下质心能量为s=14TeV的碰撞，对应的积分光度为1000fb−1。利用蒙特卡罗模拟在有效场论（EFT）框架内解释，这项工作研究了新物理的潜在特征。在没有这些信号的情况下，对关键的EFT参数设置了上限，包括理论的截止尺度和Z '玻色子的质量。

Probing a novel neutral heavy gauge boson within the mono-Z′ portal at the HL-LHC

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

\sqrt{s} = 14 TeV

under high-luminosity conditions, corresponding to an integrated luminosity of

1000 {fb}^{- 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.
