论文摘要
我们考虑了由新的伪层粒子介导的高高能量中微子通量介导的活动性秘密中微子相互作用的影响。特别是，我们专注于3个活性和1个无菌中微子，结合了依赖风味的相互作用，扩大了我们最近检查的1个活性和1个无菌中微子的情况。我们发现，根据无菌中微子与活性部门的相互作用的类型，现在允许秘密相互作用的参数空间的新区域，从而导致对我们考虑的两个基准通量的有趣现象学含义，即在100 pev和A a a天文物理功率法律范围内，在100 pev和a a a in opogenig flux范围内，以及超级富含的范围。首先，最终的活性通量可以在未来的实验中呈现可观察到的可测量耗竭。尤其是，在只有Tau Neutrino相互作用的情况下，我们发现对天体物理功率法通量的影响可能很大，以至于Icecube实验已经探测了。此外，我们发现风味比能量依赖性的有趣特征。
We consider the effects of active-sterile secret neutrino interactions, mediated by a new pseudoscalar particle, on high- and ultra high-energy neutrino fluxes. In particular, we focus on the case of 3 active and 1 sterile neutrino coupled by a flavor dependent interaction, extending the case of 1 active and 1 sterile neutrino we have recently examined. We find that, depending on the kind of interaction of sterile neutrino with the active sector, new regions of the parameter space for secret interactions are now allowed leading to interesting phenomenological implications on two benchmark fluxes we consider, namely an astrophysical power law flux, in the range below 100 PeV, and a cosmogenic flux, in the Ultrahigh energy range. First of all, the final active fluxes can present a measurable depletion observable in future experiments. Especially, in the case of only tau neutrino interacting, we find that the effects on the astrophysical power law flux can be so large to be already probed by the IceCube experiment. Moreover, we find intriguing features in the energy dependence of the flavor ratio.
