We study the prospect of heavy singlet neutrinos as a dark matter (DM) candidate within a neutrinophilic U(1) model, where the Standard Model (SM) is extended with a U(1) gauge symmetry, and neutrino mass and oscillation parameters are explained through an inverse see-saw mechanism. The lightest of the heavy neutrinos plays the role of the DM while the newly introduced scalars and the extra gauge boson Z' act as mediators between the dark sector and the SM sector. We show the range of model parameters where this DM candidate can be accommodated in the Weakly Interacting Massive Particle (WIMP) or Feebly Interacting Massive Particle (FIMP) scenario. The observed DM relic density is achieved via the new gauge boson and singlet scalar portals in the WIMP scenario whereas within the FIMP scenario, these two particles assume a distinct yet pivotal role in generating the observed relic density of dark matter.

  1. Probing Neutrinophilic Long-Range Forces at DUNE

    hep-ph 2026-07 conditional novelty 6.0

    DUNE's long baseline can exclude previously unexplored regions of neutrinophilic long-range force parameter space and map them onto cosmologically relevant neutrino self-interaction strengths.

  2. Formation of Asymmetrical Two-Brane Structure and its Possible Manifestation

    hep-th 2025-02 unverdicted novelty 3.0

    In a two-brane model, brane asymmetry produces different fermion masses, allowing superheavy leptons on the second brane to act as dark matter without fine-tuning.
