Abstract

The potential of the dark matter direct detection experiments to provide independent measurements on solar neutrino fluxes in the Standard Model and in the presence of the light mediators is studied in this work. We also present the sensitivity of direct detection experiments on light mediators with solar neutrinos. We find that the sensitivities on ⁸B and pp neutrino fluxes can reach

\pm 10 %

with improved backgrounds and systematic uncertainties and they can be further pushed to

\pm 3 %

with a increased exposure. The constraints on light mediators can reach

O (10^{- 6})

for the masses of scalar and vector mediators below 10 MeV. However, the presence of scalar or vector mediators could lead to shifts in the best fit value of ⁸B fluxes, which will increase the challenges in the precise measurements of solar neutrino fluxes with direct detection experiments.

在存在光介质的直接探测实验中测量太阳中微子通量

这项工作研究了暗物质直接探测实验在标准模型和轻介质存在的情况下对太阳中微子通量提供独立测量的潜力。我们还介绍了太阳中微子轻介质直接探测实验的灵敏度。我们发现，随着背景和系统不确定性的改善，8B 中微子和 pp 中微子通量的灵敏度可以达到 ±10%，而随着暴露量的增加，灵敏度可以进一步提高到 ±3%。当标量和矢量介质的质量低于 10 MeV 时，对轻介质的约束可以达到 O(10-6)。然而，标量或矢量介质的存在可能导致 8B 通量最佳拟合值的偏移，这将增加直接探测实验精确测量太阳中微子通量的挑战。

期刊介绍： Nuclear Physics B focuses on the domain of high energy physics, quantum field theory, statistical systems, and mathematical physics, and includes four main sections: high energy physics - phenomenology, high energy physics - theory, high energy physics - experiment, and quantum field theory, statistical systems, and mathematical physics. The emphasis is on original research papers (Frontiers Articles or Full Length Articles), but Review Articles are also welcome.
