Light Neutrinophilic Dark Matter from a Scotogenic Model
arXiv:2307.15760 · doi:10.1016/j.physletb.2023.138167
Abstract
We present a minimal sub-GeV thermal Dark Matter (DM) model where the DM primarily interacts with neutrinos and participates in neutrino mass generation through quantum loop corrections at one-loop level. We discuss the challenges in achieving this in the scotogenic framework and identify a viable variant. Due to minimality and the interplay between obtaining the correct DM relic abundance and neutrino oscillation data, the model predicts (i) a massless lightest neutrino, (ii) enhanced rate of decay due to loop corrections involving light DM exchange, and (iii) testable lepton flavor-violating signal . Detecting monoenergetic neutrinos from DM annihilation in next-generation neutrino detectors offers a promising way to test this scenario.
