AI 中文摘要
TeV 量级的缪子对撞机能够通过在环的直线段中缪子衰变产生高度准直的高能中微子束流。近期研究表明，这些中微子可借助专用的远向前中微子探测器用于中微子物理的高精度测量。在本研究中，我们探讨了缪子对撞机发现稀有中微子三叉戟过程的潜力，该过程的特征是来自中微子的弱玻色子与来自靶核库仑场的光子发生融合。我们的结果表明，在基线 10 kg 中微子探测器中，对于末态带电轻子不同味组合的配置，每年中微子三叉戟事例率较大 [$\mathcal{O}(10^3)$]，这将允许对标准模型进行高精度检验并搜寻新物理。作为第一个例子，我们研究了由 $L_\mu - L_\tau$ 模型预言的新规范玻色子 $Z'$ 的影响，并推导了对此新规范玻色子的预期灵敏度。我们的发现表明，缪子对撞机上的中微子探测器将显著扩展当前参数空间中的排除区域。
英文摘要
A TeV-scale muon collider enables the production of a highly collimated high-energy neutrino flux by muon decay in the straight sections of the collider ring. Recent studies have demonstrated that these neutrinos can be used for high-precision measurements in neutrino physics with a dedicated far-forward neutrino detector. In this study, we investigate the potentiality of the muon collider to discover the rare neutrino trident process, which is characterized by the fusion between a weak boson from the neutrino and a photon from the Coulomb field of the nucleus target. Our results indicate large neutrino trident rates per year [$\mathcal{O}(10^3)$] in a baseline 10 kg neutrino detector for a configuration of different flavour pairs of charged leptons in the final state, which will allow high-precision tests of the Standard Model and searches for New Physics. As a first example, we investigate the impact of the a new gauge boson $Z'$, as predicted by the $L_μ- L_τ$ model, and derive the projected sensitivity to this new gauge boson. Our findings show that a neutrino detector at a muon collider will significantly extend the current excluded regions of the parameter space.
