AI总结:

本文研究了未来 $e^-p$ 对撞机中 $W^{\prime}$ 玻色子的性质,探讨了其与电子-质子碰撞过程的相互作用,发现其在特定参数空间下的可探测质量和耦合强度,并指出 $e^- u \to e^+ jjj$ 过程可能为左手-右手对称模型提供证据。

摘要:

作为标准模型之外新物理的强候选者,奇异带电规范玻色子 $W^{\prime}$ 已经引起了广泛研究兴趣。在本工作中,我们研究了 $W^{\prime}$ 玻色子在电子-质子对撞机中的相互作用。研究了过程 $e^- u \to ν_e d$ 和 $e^- u \to e^\pm jjj$ 以及 $t$-通道 $W^{\prime}$ 交换的相互作用。初始态电子的极化对所研究过程的截面有显著影响,而最终态轻子的角分布则成为 $W^{\prime}$ 玻色子相互作用的重要可观测量。在某些特定的参数空间区域,$W^{\prime}$ 玻色子的可探测质量范围可以达到约 10 TeV,耦合强度可以达到标准模型相互作用强度的约 1% 的精度。特别是,$e^- u \to e^+ jjj$ 过程在标准模型内是被禁止的,这将构成寻找左手-右手对称模型的重要证据。

英文摘要:

As a strong candidate for new physics beyond the Standard Model, the exotic charged gauge boson $W^{\prime}$ has attracted extensive research interest. In this work we investigate the interactions of the $W^{\prime}$ boson at the electron-proton colliders. The process $e^- u \to ν_e d$ and $e^- u \to e^\pm jjj$ with $t$-channel $W^{\prime}$ exchange are studied. The polarization of the initial-state electrons has a significant impact on the cross section of the studied process, while the angular distribution of the final-state leptons serves as an important observable for the interactions of the $W^{\prime}$ boson. In some specific regions of the parameter space, the detectable mass range for the $W^{\prime}$ boson can reach around 10 TeV, and the coupling strength can achieve a precision of approximately 1\% relative to the interaction strength of the Standard Model. Especially, $e^- u \to e^+ jjj$ process is forbidden within the Standard Model, which would constitute important evidence in the search for the Left-Right Symmetric Model.
