AI总结:

本文推导了在 $U(1)_{L_μ-L_τ}$ 对称性下带电轻暗物质的电子反冲直接探测限制,评估了 XLZD 和 OSCURA 实验封闭同时解释 μ 子反常磁矩与暗物质遗迹密度参数空间的前景,并补充讨论了先前被忽略的自旋相关散射贡献。

摘要:

标准模型的一种可能扩展是增加一个规范 $U(1)_{L_μ-L_τ}$ 对称性,这能够解释最近对 μ 子反常磁矩的测量结果。如果暗物质粒子在这种对称性下带电,新规范玻色子与光子之间的动能混合会诱发暗物质-电子相互作用。我们利用电子反冲实验推导了对在 $U(1)_{L_μ-L_τ}$ 对称性下带电的轻暗物质的直接探测限制,并探索了利用 XLZD 和 OSCURA 关闭能同时解释最近 μ 子反常磁矩测量结果与观测到的暗物质遗迹密度的参数空间的前景。我们进一步讨论了该模型中产生的自旋相关散射贡献,这在先前的文献中被忽略了。

英文摘要:

A possible extension of the Standard Model able to explain the recent measurement of the anomalous magnetic moment of the muon consists in adding a gauged $U(1)_{L_μ-L_τ}$ symmetry. If the dark matter particle is charged under this symmetry, the kinetic mixing between the new gauge boson and the photon induces dark matter-electron interactions. We derive direct detection constraints on light dark matter charged under a $U(1)_{L_μ-L_τ}$ symmetry with electron recoil experiments, and explore prospects with XLZD and OSCURA to close in the parameter space able to explain simultaneously the recent measurement on the anomalous magnetic moment of the muon and the observed relic density of dark matter. We further discuss the spin-dependent scattering contribution arising in this model, which was ignored previously in the literature.
