论文摘要
tau中微子可能是SM中研究最少的粒子，到目前为止，只有少数几个相互作用事件。这可能部分归因于其在SM中的较小的生产率，这主要是通过D_S梅森腐烂发生的。但是，这也使tau中微子通量测量成为其他新物理生产模式的有趣实验室。在这项研究中，我们研究了在光载体玻色子衰减中tau中微子产生的可能性。我们考虑与B-l-l_mu-2l_tau，B-L_E-2L_TAU和B-3L_TAU数字相对应的无异常U（1）量规组的四个方案，分析当前对参数空间的约束，并探索Donut以及未来的Emuls tecter ftector ferments faserne fasernun@snd@lhc@lhuc@lhc@lhc@lhuc@snd@lhc@lhc@lhc@lhc@nd@nd@nd@nd@nd@nd@nd@nd@nd@nd@nd@。我们发现，这些实验在参数空间的一部分中提供了领先的直接约束，尤其是当向量玻色子的质量接近欧米茄中的质量时。
The tau neutrino is probably the least studied particle in the SM, with only a handful of interaction events being identified so far. This can in part be attributed to their small production rate in the SM, which occurs mainly through D_s meson decay. However, this also makes the tau neutrino flux measurement an interesting laboratory for additional new physics production modes. In this study, we investigate the possibility of tau neutrino production in the decay of light vector bosons. We consider four scenarios of anomaly-free U(1) gauge groups corresponding to the B-L, B-L_mu-2L_tau, B-L_e-2L_tau and B-3L_tau numbers, analyze current constraints on their parameter spaces and explore the sensitivity of DONuT and as well as the future emulsion detector experiments FASERnu, SND@LHC an SND@SHiP. We find that these experiments provide the leading direct constraints in parts of the parameter space, especially when the vector boson's mass is close to the mass of the omega meson.
