Query: Singlet-Doublet Self-interacting Dark Matter and Radiative Neutrino Mass   Self-interacting dark matter (SIDM) with a light mediator is a promising
scenario to alleviate the small-scale problems of the cold dark matter paradigm
while being consistent with the latter at large scales, as suggested by
astrophysical observations. This, however, leads to an under-abundant SIDM
relic due to large annihilation rates into mediator particles, often requiring
an extension of the simplest thermal or non-thermal relic generation mechanism.
In this work, we consider a singlet-doublet fermion dark matter scenario where
the singlet fermion with a light scalar mediator gives rise to the
velocity-dependent dark matter self-interaction through a Yukawa type
attractive potential. The doublet fermion, by virtue of its tiny mixing with
the singlet, can be long-lived and can provide a non-thermal contribution to
the singlet relic at late epochs, filling the deficit in the thermal relic of
singlet SIDM. The light scalar mediator, due to its mixing with the standard
model Higgs, paves the path for detecting such SIDM at terrestrial laboratories
leading to constraints on model parameters from CRESST-III and XENON1T
experiments. Enlarging the dark sector particles by two more singlet fermions
and one scalar doublet, all odd under an unbroken $\mathcal{Z}_2$ symmetry can
also explain non-zero neutrino mass in scotogenic fashion.
