The extension of the standard model with a multiplicative $U{\left(1\right)}_R$ factor is consistent with a light vector boson. In its simplest realization, only right-handed particles carry charges of the new group. In this model, there is a residual ${\tau }_{3R}$ symmetry and one new coupling constant which correlates neutrino interactions. We compute new contributions to antineutrino–electron scattering and coherent scattering on nuclei, and compare them with the XENON1T result.

与中微子反应相关的光介体

标准模型的乘法扩展 $你{\left(1\right)}_{\mathrm{电阻}}$因子与光矢量玻色子一致。在最简单的实现中，只有右手粒子携带新群的电荷。在这个模型中，有一个残差${\tau }_{3\mathrm{电阻}}$对称性和一个与中微子相互作用相关的新耦合常数。我们计算了对原子核上的反中微子电子散射和相干散射的新贡献，并将它们与 XENON1T 结果进行比较。
