abstract

We consider a fermionic dark matter (DM) in the left-right symmetric framework by introducing a pair of vector-like (VL) doublets in the particle spectrum. The stability of the DM is ensured through an unbroken $\mathcal{Z}_2$ symmetry. We explore the parameter space of the model compatible with the observed relic density and direct and indirect detection cross sections. The presence of charged dark fermions opens up an interesting possibility for the doubly charged Higgs signal at LHC and ILC. The signal for the doubly charged scalar decaying into the dark sector is analyzed in multilepton final states for a few representative parameter choices consistent with DM observations.

    hep-ph 2025-09 conditional novelty 6.0 of 10

    A vector-like lepton dark matter model with two inert scalar leptoquarks produces a radiative pseudo-Dirac mass splitting that evades direct detection and opens up parameter space for the correct relic density.

  2. Exploring two component doublet dark matter

    A two-component model with an inert scalar doublet and a pseudo-Dirac fermion doublet can match Planck relic density and direct and indirect limits in sub-TeV mass regions, and a type-II seesaw triplet can also genera...
