We consider a multicomponent dark matter model where the dark sector contains a scalar
doublet and a complex scalar singlet. We impose a discrete Z 4 symmetry to ensure such …

A bstract We investigate an extension of the Standard Model (SM) with two candidates for
dark matter (DM). One of them is a real scalar field and the other is an Abelian gauge field …

A bstract We study the interaction between the inert Higgs doublet (IDM) dark matter and a
vector-like SU (2) triplet lepton (VLL), both of which are Z 2-odd. The vector current of the …

A bstract We consider an extension of the Standard Model that explains the neutrino masses
and has a rich dark matter phenomenology. The model has two dark matter candidates, a …

A bstract We investigate ways of identifying two kinds of dark matter (DM) component
particles at high-energy colliders. The strategy is to notice and distinguish double-peaks …

If coupled feebly to the Standard Model bath, dark matter can evade the severe constraints
from the direct search experiments. At the same time, such interactions help produce dark …

We examine the impact of a faster expanding Universe on the phenomenology of scalar
dark matter (DM) associated with SU (2) L multiplets. Earlier works with a radiation …

A bstract We investigate, for the first time, a scenario where the dark matter consists of three
complex scalar fields that are stabilized by a single Z 7 symmetry. As an extension of the …

We study an extension of the Standard Model (SM) which could have two candidates for
dark matter (DM) including a Dirac fermion and a vector dark matter (VDM) under a new U …

In one-component dark matter (DM) scenarios is commonly assumed that a scalar weakly
interacting massive particle must either be part of an SU (2) L multiplet with zero …
