Dark matter Z' and XENON1T excess from U(1)X extended standard model
Abstract
Motivated by the excess in the electronic recoil energy spectrum reported by the XENON1T collaboration, we propose a light dark matter (DM) scenario in which the $$U(1)_X$$ gauge boson $$Z^\prime$$ behaves as a DM particle in the universe. We show that $$Z^\prime$$ with a mass of a few keV and a $$U(1)_X$$ gauge coupling $$g_X \simeq 10^{-16}$$ can nicely fit the excess. This model also accommodates successful cosmic inflation with the $$U(1)_X$$ breaking Higgs field as the inflaton.
