Probing superheavy dark matter with gravitational waves
Abstract We study the superheavy dark matter (DM) scenario in an extended B−L model, where one generation of right-handed neutrino ν R is the DM candidate. If there is a new lighter sterile neutrino that co-annihilate with the DM candidate, then the annihilation rate is exponentially enhanced, allow...
