摘要:

中微子的Majorana性质长期以来一直是探索超出标准模型可能新物理的焦点,这激发了许多专门的理论和实验研究。未来的同号μ子对撞机是通过轻子数破坏过程寻找Majorana中微子的理想平台。具体而言,这种t道过程在运动学上受到的抑制较小,在探测高达10 TeV高质量区的Majorana中微子方面具有良好优势。本文通过检查三种不同的末态进行了详细的快速Monte Carlo模拟研究:1)包含电子或μ子的纯轻子态,2)半轻子态,3)解析或合并类别中的纯强子态。此外,我们对纯轻子末态进行了完整模拟研究,以验证快速模拟结果。

英文摘要:

Majorana properties of neutrinos have long been a focus in the pursuit of possible new physics beyond the standard model, which has motivated lots of dedicated theoretical and experimental studies. A future same-sign muon collider is an ideal platform to search for Majorana neutrinos through the Lepton Number Violation process. Specifically, this t-channel kind of process is less kinematically suppressed and has a good advantage in probing Majorana neutrinos at high mass regions up to 10 TeV. In this paper, we perform a detailed fast Monte Carlo simulation study through examining three different final states: 1) pure-leptonic state with electrons or muons, 2) semi-leptonic state, and 3) pure-hadronic state in the resolved or merged categories. Furthermore, we perform a full simulation study on the pure-leptonic final state to validate our fast simulation results.
