摘要

多tev μ介子对撞机提供了一种强大的手段来获取与μ介子耦合的新物理，同时通过μ介子衰变产生干净而强烈的高能中微子束。我们研究了一个利用中微子束和指向介子对撞机相互作用点的前向探测器的固定目标实验。对中微子自相互作用的敏感性进行了可行性研究，重点研究了与标准模型中微子完全耦合的轻子标量φ。我们的工作表明，来自主探测器和前向探测器的投影可以将现有的极限提高两个数量级，超过其他未来的实验。

Searching for neutrino self-interactions at future muon colliders

Multi-TeV muon colliders offer a powerful means of accessing new physics coupled to muons while generating clean and intense high-energy neutrino beams via muon decays. We study a fixed-target experiment leveraging the neutrino beams and a forward detector pointing at the interaction point of the muon collider. The sensitivity to neutrino self-interactions is analyzed as a feasibility study, focusing on the leptonic scalar ϕ exclusively coupled to the Standard Model neutrinos. Our work shows that projections from both the main and forward detectors can enhance the existing limits by two orders of magnitude, surpassing other future experiments.
