论文摘要
我们研究了无菌中微子的特征,该特征是在伴随中微子领域的轻孔玻色子$ x^μ$的存在。小说在活动性 - 激进的中微子混合$ |上的界限u _ {\ ell 4} |^2 $,尤其是对于tau风味($ l =τ$),探索了各种对撞机和固定目标实验。另外,考虑到无菌中微子的附加衰减通道进入光量表玻色子($ν_4\ toν_\ ell e^+ e^ - $),我们探索并约束了中微子振荡实验中低能量过量的参数空间。
We investigate features of the sterile neutrinos in the presence of a light gauge boson $X^μ$ that couples to the neutrino sector. The novel bounds on the active-sterile neutrino mixings $| U_{\ell 4} |^2$, especially for tau flavor ($l = τ$), from various collider and fixed target experiments are explored. Also, taking into account the additional decay channel of the sterile neutrino into a light gauge boson ($ν_4 \to ν_\ell e^+ e^-$), we explore and constrain a parameter space for low energy excess in neutrino oscillation experiments.
