DESCRIPTION:Speakers: Shreyashi Chakdar\n\nIn this talk I would introduce 
 a class of dark sector models based on a chiral gauge symmetry acting on a
  dark sector. The chiral protects the masses of the dark sector fermions\,
  and also guarantees the stability of the DM by virtue of an unbroken disc
 rete gauge symmetry. We identify 38 such models which are descendants of a
  chiral gauge symmetry\, consisting of a minimal set of fermions with simp
 le charge assignments. We show how these models can also be utilized to ge
 nerate small Majorana neutrino masses radiatively via the scotogenic mecha
 nism with the dark sector particles circulating inside loop diagrams. We f
 urther explore the phenomenology of the simplest model in this class\, whi
 ch admits a Majorana fermion\, Dirac fermion or a scalar field to be the D
 M candidate\, and show the consistency of various scenarios with constrain
 ts from relic density and direct detection experiments.\n\nhttps://indico.
