摘要:

矢量轻子(VLLs)作为最引人注目的粒子之一,在标准模型(SM)的若干扩展中受到了广泛关注。本文在国际直线对撞机(ILC)上,在满足渐近安全性的模型背景下,探索通过成对产生发现矢量轻子的潜力。我们推导了质心能量为 $\sqrt{s} =$ 1 TeV、积分亮度为 $\mathcal{L}$ = 1 ab$^{-1}$ 的ILC对此类矢量轻子模型参数空间的预期灵敏度。结果表明,对于质量 $M_F$ 处于 $M_{F}\in$ [101GeV, 463GeV] 区域的矢量轻子,汤川耦合常数 $κ$ 可低至 $κ\in$ [0.032, 0.098]。

英文摘要:

Vector-like leptons (VLLs) as one kind of the most intriguing particles, have been widely concerned in several extensions of the Standard Model (SM). In this work, we explore the discovery potential of VLLs via pair production in the context of models that satisfy asymptotic safety at the International Linear Collider (ILC). The expected sensitivities of the ILC with the center of mass energy $\sqrt{s} =$ 1 TeV and the integrated luminosity $\mathcal{L}$ = 1 ab$^{-1}$ to the parameter space of this kind of VLL models are derived. The results we obtained show that, for the VLL with mass $M_F$ in the region of $M_{F}\in$ [101GeV, 463GeV], the Yukawa coupling $κ$ can be as low as $κ\in$ [0.032, 0.098].
