论文摘要
电子后退数据中最近的Xenon1T过量可以通过无异常的轴颗粒（ALP）暗物质进行解释，质量$ M_D = 2.3 \ pm 0.2 \，$ keV和衰减常数$ f_TC/q_e \ simeq 2 \ simeq 2 \ simeq 2 \ times 10^{10} {10} {10} \ sqrt {10} \ sqrt {ω____________ dm}} \，{\ rm gev} $。有趣的是，建议的质量和衰减常数与关系一致，$ f_ϕ \ sim 10^3 \ sqrt {m_ϕm_p} $，在ALP在ALP中扮演Efteraton的作用的情况下预测。这增加了ALP暗物质负责Xenon1T过量的可能性也使早期宇宙的通货膨胀促进了通货膨胀。我们研究了Xenon1t过量对通货膨胀后宇宙的ALP通胀和热历史的影响。
The recent XENON1T excess in the electron recoil data can be explained by anomaly-free axion-like particle (ALP) dark matter with mass $m_ϕ= 2.3 \pm 0.2\,$keV and the decay constant $f_ϕ/q_e \simeq 2 \times 10^{10} \sqrt{Ω_ϕ/Ω_{\rm DM}}\,{\rm GeV}$. Intriguingly, the suggested mass and decay constant are consistent with the relation, $f_ϕ\sim 10^3 \sqrt{m_ϕM_p}$, predicted in a scenario where the ALP plays the role of the inflaton. This raises a possibility that the ALP dark matter responsible for the XENON1T excess also drove inflation in the very early universe. We study implications of the XENON1T excess for the ALP inflation and thermal history of the universe after inflation.
