AI 中文摘要
尽管缪子对撞机主要被视为在能量前沿开展新物理搜寻的精密装置，但它们同时也是强流的高能中微子源。大量电子中微子和缪子中微子由束流缪子的衰变产生，尤其在实验周围的直线段区域。本研究采用最新设计的10 TeV缪子对撞机重新评估这些中微子通量，发现对撞区域附近的通量几乎比早期估计值高两个数量级。我们还计算了μ⁺μ⁻对撞产生的中微子通量、缪子衰变产生的电子引发的电磁簇射，以及对撞机环附近中微子相互作用产生的中微子通量。研究发现，这些额外的中微子源不可忽略，会在置于前向方向的吨级探测器中产生相当数量的各味中微子相互作用，包括数个τ中微子事例。我们探讨了缪子对撞机中微子在量子色动力学与核物理、电弱精密测量以及新物理搜寻方面提供的物理机遇。
英文摘要
While muon colliders are primarily considered precision machines for new physics searches at the energy frontier, they are also intense sources of high-energy neutrinos. Large fluxes of electron and muon neutrinos are produced in the decay of beam muons, especially along the straight sections around the experiments. In this work, we re-evaluate these neutrino fluxes using the latest design of a \SI{10}{TeV} muon collider and find that fluxes around the interaction region are almost two orders of magnitude higher than earlier estimates. We also compute the fluxes of neutrinos produced in $μ^+μ^-$ collisions, electromagnetic showers induced by electrons from muon decay, and interactions of neutrinos close to the collider ring. We find that these additional neutrino sources are non-negligible and would lead to a sizable number of neutrino interactions of all flavors, including several tau neutrino events, in a ton-scale detector placed in the forward direction. We discuss the physics opportunities offered by muon collider neutrinos in the context of QCD and nuclear physics, electroweak precision measurements, and searches for new physics.
