νR Dark matter-philic Higgs for 3.5 keV X-ray signal
We suggest a new model of 7 keV right-handed neutrino dark matter inspired by a recent observation of 3.5 keV X-ray line signal in the XMM-Newton observatory. It is difficult to derive the tiny masses with a suitable left–right mixing of the neutrino in a framework of ordinary simple type-I seesaw m...
