论文摘要
我们研究了早期宇宙宇宙学与暗物质直接检测之间的相互作用，考虑到具有自然抑制耦合光子的轴突模型。在电子量表的宇宙学放松背景下，我们专注于\ emph {放松暗物质}的场景，其中放松场构成了所有观察到的暗物质遗物密度及其允许的质量范围固定在几个$ \ mathrm {kev} $ bious construction中。特别是，我们表明，具有质量$ m_ϕ = 3.0 \，\ mathrm {kev} $的松弛粒子将其与$ g_ {ϕ，e}，e} = 6.8 \ times 10^{ - 14} $相结合的电子与Xenon1t的过剩一致，同时对经过的深色的深色物质和满足的cosmo comporto和cosmo cobsy cocmo copsmo copsmo和满意。这种情况使用电动量表作为链接在早期将放松产生与直接检测中的暗物质吸收率连接起来。
We investigate the interplay between early universe cosmology and dark matter direct detection, considering axion models with naturally suppressed couplings to photons. In the context of the cosmological relaxation of the electroweak scale, we focus on a scenario of \emph{Relaxion Dark Matter}, in which the relaxion field constitutes all the observed dark matter relic density and its allowed mass range is fixed to a few $\mathrm{keV}$ by construction. In particular, we show that a relaxion particle with mass $m_ϕ= 3.0 \,\mathrm{keV}$ which couples to electrons with $g_{ϕ, e}= 6.8 \times 10^{-14}$ is consistent with the XENON1T excess, while accounting for the observed dark matter and satisfying astro/cosmo probes. This scenario uses the electroweak scale as the link connecting the relaxion production at early times with the dark matter absorption rate in direct detection.
