Thermally modified sterile neutrino portal dark matter and gravitational waves from phase transition: the freeze-in case
Abstract We consider the thermal effects into the evaluation of the dark matter production process. With the assistance of the right handed neutrinos, the freeze-in massive particle dark matter production history can be modified by the two-step phase transitions. The kinematic of decay/inverse decay...
