摘要：
We perform an exclusive study on the feebly interacting massive particle dark matter candidate in an extended hyperchargeless (Y = 0) Higgs triplet model. The additional Z2 odd neutral fermion singlet plays the role of dark matter with support from two other vectorlike fermion doublets. The mixing between the neutral component of a doublet and singlet fermions controls the current relic density through the freeze-in mechanism, whereas the additional doublet fermion helps to get the neutrino mass and mixing angles. We obtain a broad region of the parameter spaces satisfying the current relic density and neutrino mass and mixing angles.
