Radiative Seesaw Dark Matter

Abstract

The singlet majoron model of seesaw neutrino mass is appended by one dark Majorana fermion singlet $\chi$ with $L=2$ and one dark complex scalar singlet $\zeta$ with $L=1$. This simple setup allows $\chi$ to obtain a small radiative mass anchored by the same heavy right-handed neutrinos, whereas the one-loop decay of the standard-model Higgs boson to $\chi \chi +\bar{\chi }\bar{\chi }$ provides the freeze-in mechanism for $\chi$ to be the light dark matter of the Universe.
