Description
In light of the negative results from WIMP search experiments, attention has shifted toward light thermal DM. Moreover, light DM has the potential to address the core-cusp problem with its large self-scattering rate. However, such models may also predict a high annihilation rate, which could be constrained severely by gamma-ray telescopes. In our study, we explored the possibility of neutrinophilic DM within the U(1)B-L extension of the Standard Model. We conducted a phenomenological analysis of this model to identify viable parameter sets that explain the relic abundance via the freeze-out mechanism, resolve the core-cusp problem, and remain consistent with current observational constraints.
