摘要: We consider the absorption by bound electrons of dark matter in form photons and axion-like particles, as well from Sun, current next-generation direct detection experiments. Experiments sensitive to electron recoils can detect such particles with masses between a few eV more than 10 keV. For photon matter, we update previous based on XENON10 data derive new bounds XENON100 CDMSlite. find these experiments disfavor previously allowed parameter space. Moreover, sensitivity projections for SuperCDMS at SNOLAB silicon germanium targets, various possible scintillating targets (cesium iodide, sodium gallium arsenide). The projected probe large regions same direction improves known direct-detection constraints but does not space beyond stellar cooling bounds. However, sensitivities upcoming using go even consistent hints white dwarf luminosity function. similar results sun. all cases, have unprecedented dark-sector particles.
