Freeze-in production of sterile neutrino dark matter in a gauged U(1)‧ model with inverse seesaw
Poddar, Tanmay Kumar; Das, Arindam; Goswami, Srubabati +1 more
We consider a general, anomaly free U(1)‧ extension of the Standard Model (SM) where the neutrino mass is generated at the tree level via the inverse seesaw mechanism. The model contains three right handed neutrinos, three additional singlet fermions, one extra complex scalar and a neutral gauge boson (Z‧). Instead of resorting to a specific U(1) …
