Dark matter in a charged variant of the Scotogenic model

Understand

Scotogenic models are among the most popular possibilities to link dark matter and neutrino masses.

• In this work we discuss a variant of the Scotogenic model that includes charged fermions and a doublet with hypercharge $3/2$.
• Neutrino masses are induced at the one-loop level thanks to the states belonging to the dark sector.
• However, in contrast to the standard Scotogenic model, only the scalar dark matter candidate is viable in this version.
