Book Description
XENON1T collaboration has reported an excess of electron recoil events last year over the background in the recoil energy in a range 1-7 keV, peaked around 2.4 keV. We apply the one-loop radiative seesaw model which was proposed by E.Ma in 2006 to provide an explanation for the XENON1T anomaly. The model consists two limits that lead to two different dark matter candidates, namely scalar particle e0 and right-handed neutrino Nk respectively, depending on their mass scales. We confirm that one of two limits can be simultaneously reconcile the XENON1T anomaly and the tiny neutrino masses with the feasible Yukawa coupling constant. Furthermore, the other parameters are also in the allowed region by experimental limitations.
