论文摘要
许多新的物理场景预测了额外的充电仪表$ W'$的存在，这可以诱导带电的电流（CC）非标准中微子相互作用（NSI）。我们通过考虑$ w'$对违反Lepton风味的贡献（LFV）衰减$ \ ell_ {i} \ rightArrow \ ell_ {J}γ$，纯净的Leptonic风味保存（FC）腐败$ \ ell_ ir_ {ii} i。 \ ell_ {j}ν_{i} \ bar {ν_{j}} $，带电的Pion Meson的衰变，半蛋白质$τ$衰减以及超允许的$β$衰减。我们发现，对纯净性CC NSI的约束通常比第一代夸克的CC NSI强。 CC NSI的最严格约束是由LFV衰减$μ\ rightarrowEγ$引起的。
Many new physics scenarios predict the existence of the extra charged gauge boson $ W'$, which can induce the charged-current (CC) non-standard neutrino interactions (NSI). We investigate the constraints on the CC NSI in model-independent fashion via considering the $ W'$ contributions to the lepton flavor violating (LFV) decays $\ell_{i}\rightarrow \ell_{j}γ$, the pure leptonic flavor conservation (FC) decays $\ell_{i}\rightarrow \ell_{j}ν_{i}\bar{ν_{j}}$, leptonic decays of charged pion meson, semileptonic $τ$ decays, and superallowed $β$ decays. We find that the constraints on the pure leptonic CC NSI are generally stronger than the ones for the CC NSI with first generation quarks. The most stringent constraints on the CC NSI arise from the LFV decay $μ\rightarrow eγ$.
