There are many possible reasons that we have not yet detected dark matter: it could be very weakly interacting, too light to trigger conventional detectors, or very massive and thus rare. But another possibility is that dark matter may scatter predominantly inelastically with Standard Model particles. In a typical model, elastic scattering is absent at tree level, and a relatively light dark...
Cosmic filaments form the structure of the cosmic web, with dark matter making up the majority of their mass. If GeV-scale dark matter particles in filaments decay into electron-positron pairs, they could generate radio waves through synchrotron radiation. A realistic description of the expected dark matter decay signals from cosmic filaments requires a detailed characterization of the dark...
We propose a novel approach to utilize knockout neutrons from dark-matter interaction with a nucleus in neutrino experiments, while previous studies have focused on recoiling protons. This method is especially crucial for water Cerenkov detectors, where high proton Cerenkov threshold (~1 GeV) suppresses signal acceptance. The knockout neutrons produce gamma rays when captured by medium, which...
