论文摘要
我们提出了一个$ su（3）_c \ times su（2）_l \ times u（1）_ {y} \ times u（1）_ {b-l} $模型，其中可以通过$ I（1）_ {b-l} $ breaking生成中微子群众和混合。轻型调解人出现并实现了违反Lepton数字的非标准相互作用。我们表明，在该模型中出现了非标准中微子相互作用，并且可以导致太阳中微子通量导致低能量后坐力事件。在包括Xenon1t，Pandax和Xenonnt在内的最新直接检测实验中，使用KEV范围电子后坐力事件进行分析。最近的直接检测观测结果导致上界的上微子与电子和中微子的组合耦合强度为$ \ sqrt {y'_ty_e} <0.5 \ 0.5 \ times 10^{ - 6} $。
We propose an $SU(3)_C\times SU(2)_L\times U(1)_{Y}\times U(1)_{B-L}$ model, in which the neutrino masses and mixings can be generated via Type-I seesaw mechanism after $U(1)_{B-L}$ breaking. A light mediator emerges and enables non-standard interaction that violates the lepton number. We show that the non-standard neutrino interaction emerges in this model, and it can lead to low energy recoil events with the solar neutrino flux. Analyses are performed with the keV range electron recoil events at recent direct detection experiments, including XENON1T, PANDAX and XENONnT. Recent direct detection observations lead to upper bound on the combined coupling strength to electron and neutrino to $\sqrt{y'_νy_e} < 0.5 \times 10^{-6}$.
