论文摘要
暗物质（DM）直接检测实验正在进入多吨时代，并将对太阳中微子的相干弹性中微子核散射（CE $ν$ ns）敏感，从而有可能探索低能量范围内的光中微子的贡献。在本文中，我们考虑了轻型介体模型（标量，向量和轴向矢量）以及对太阳中微子CE $ν$ ns过程的相应贡献。由新一代DM直接检测实验的现状和未来计划的当前状态，我们研究了在不同核靶标和检测器技术的DM直接检测实验中光介体的敏感性。还得出了Xenon-1T的最新$^8 $ B太阳中微子测量的约束。最后，我们表明，太阳中微子CE $ν$ ns流程可以对$L_μ-L_τ$模型具有严格的限制，矢量介体质量低于100 MEV，涵盖了解决方案的可行参数空间，以$（g-2）_μ$异常。
Dark matter (DM) direct detection experiments are entering the multiple-ton era and will be sensitive to the coherent elastic neutrino nucleus scattering (CE$ν$NS) of solar neutrinos, enabling the possibility to explore contributions from new physics with light mediators at the low energy range. In this paper we consider light mediator models (scalar, vector and axial vector) and the corresponding contributions to the solar neutrino CE$ν$NS process. Motivated by the current status of new generation of DM direct detection experiments and the future plan, we study the sensitivity of light mediators in DM direct detection experiments of different nuclear targets and detector techniques. The constraints from the latest $^8$B solar neutrino measurements of XENON-1T are also derived. Finally, We show that the solar neutrino CE$ν$NS process can provide stringent limitation on the $ L_μ-L_τ $ model with the vector mediator mass below 100 MeV, covering the viable parameter space of the solution to the $ (g-2)_μ$ anomaly.
