论文摘要
可以在太阳中产生轴突状颗粒（阿尔卑斯山），被认为是宇宙暗物质（DM）的可行候选者。它可以腐烂成两个光子或与物质相互作用。我们确定了由于原子激发和电离引起的逆Primakoff过程的新的非弹性通道。它们的横截面是通过合并原子电荷和当前密度的完整电磁场来得出的，并通过基准的原子多体型方法计算得出。分析了地下Xenonnt和表面Texono实验的补充数据。事件速率和灵敏度达到有关太阳和DM-ALP的评估。 ALP耦合中与光子与ALP质量的新参数空间（1〜EV $ - $ 10〜KEV）以前无法访问实验室实验，并用太阳能ALP探测并排除。但是，在DM-ALP衰减的区域，将没有ALP升华，因此在直接搜索实验中的检测器中没有相互作用。没有物理限制可以得出。未来的项目将能够逃避DM-ALP的稳定性和打开新的可观察窗口（100〜EV $ -1〜MEV）。
Axionlike particles (ALPs) can be produced in the Sun, and are considered viable candidates for the cosmological dark matter (DM). It can decay into two photons or interact with matter. We identify new inelastic channels of inverse Primakoff processes due to atomic excitation and ionization. Their cross sections are derived by incorporating full electromagnetic fields of atomic charge and current densities, and computed by well-benchmarked atomic many-body methods. Complementing data from the underground XENONnT and surface TEXONO experiments are analyzed. Event rates and sensitivity reaches are evaluated with respect to solar- and DM-ALPs. New parameter space in ALP couplings with the photons versus ALP masses in (1~eV$-$10~keV) not previously accessible to laboratory experiments are probed and excluded with solar-ALPs. However, at regions where DM-ALPs have already decayed, there would be no ALP-flux and hence no interactions at the detectors in direct search experiments. No physics constraints can be derived. Future projects would be able to evade the stability bound and open new observable windows in (100~eV$-$1~MeV) for DM-ALPs.
