本研究通过多弱规范玻色子产生探测硬散射过程，利用高亮度碰撞机探索新物理现象，通过优化信号与背景比实现有效信号分离。

摘要：

检测新物理现象粒子的一种可能方法是研究强规范玻色子产生作为质子-质子散射的结果。本研究包括在多TeV能量和积分亮度L=3000 fb^-1条件下，质子-质子束之间硬散射产生的多个弱规范玻色子的产生。对双、三、四次散射机制的有效产生截面作为sqrt(s)函数进行了计算。质心能量从8 TeV变化到100 TeV，以涵盖未来碰撞机的能力。在所有研究过程中，三散射过程W+W-W+被选为信号过程，基于主导的截面。背景通道ZZZ、ZZZZ、W-ZZ、W+ZZ、W+W-Z、W+W-ZZ、W+W-W-ZW-W-具有相对较低的截面，从可能的散射机制中被选中以研究高亮度对低生产截面过程的影响。我们研究了不同的衰变模式。对于W和Z的轻子和强子特定衰变，每个信号和背景过程的累积效率已进行了计算。在本研究中，我们成功地展示了一种有效的背景抑制方法，通过系统地优化信号与背景的比例。结果表明，尽管高阶散射的截面较低，但独特的动力学特征使在未来的碰撞机中能够有效隔离信号。

英文摘要：

One of the possible ways to detect the new physics phenomena particles is to investigate the weak gauge boson production as a result of hadron-hadron scattering. This study comprises the production of multiple weak gauge bosons as a result of hard scattering between the proton-proton beams at multi-TeV energies and integrated luminosity $\mathcal L =$ 3000 $fb ^{-1}$. The effective production cross-sections for pair, triple, and quartic scattering mechanisms have been computed as a function of $\sqrt s$. The center of mass energy has been varied from 8 TeV to 100 TeV to encompass the future collider capabilities. Out of all the studied processes, the triple scattering process $W^+W^-W^+$ has been chosen as the signal process based on the dominant cross-section. The background channels ZZZ, ZZZZ, $W^-ZZ$, $W^+ZZ$, $W^+W^-Z$, $W^+W^-ZZ$, $W^+W^-W^+W^-$, having comparatively lower cross-sections, have been selected from possible scattering mechanisms to investigate the effect of higher luminosity on the low production cross-section processes. We have investigated the different decay modes. For both lepton and hadron-specific decays of W and Z, the cumulative efficiencies for each signal and background process have been computed. In this study, we have successfully demonstrated an effective methodology for background suppression by systematically optimizing the signal-to-background ratio. The results indicate that, despite lower cross-sections for higher-order scattering, the distinct kinematic features enable effective signal isolation at future colliders.
