论文摘要
我们研究了与新的中性仪表boson $ z $ z'$相关的活跃至重度中微子对中微子 - 核子散射的过渡性磁偶极力矩在正向搜索实验中的影响。我们将中微性中微子核子的散射（$νa\ rightarrow n a $）视为Faser $ν$的重中微子$ n $的生产机制，并估计磁性含量达到$μ__{ν_α} $的敏感性达到70， {\ rm gev} $）。在这项研究中，我们考虑了三种基准模型，其中重中微子分别为$ l_e $，$l_μ$或$L_τ$ Doublet。
We investigate the effects of the transitional magnetic dipole moment of the active-to-heavy-neutrino associated with a new neutral gauge boson $Z'$ on neutrino-nucleon scattering at the ForwArd Search ExpeRiment-$ν$ (FASER$ν$). We consider the neutral-current neutrino-nucleon scattering ($νA\rightarrow N A$) as the production mechanism of the heavy neutrino $N$ at FASER$ν$ and estimate the sensitivity reach on the magnetic moment coupling $μ_{ν_α}$ for a range of heavy neutrino mass ($1\,{\rm GeV} < M_{N} < 70 {\rm GeV}$). In this study, we consider three benchmark models, in which the heavy neutrino is coupled to $L_e$, $L_μ$ or $L_τ$ doublet, respectively.
