We introduce a 3-Higgs Doublet Model (3HDM) with two Inert (or dark) (pseudo)scalar doublets and an active Higgs one, hence termed I(2+1)HDM, in the presence of a discrete $Z_3$ acting upon the three doublet fields. Assuming a maximally symmetric configuration of the parameters related to the two dark doublets, we show that such a construct yields a two-component Dark Matter (DM) model and the two

Observed tiny masses of neutrinos suggest the existence of physics beyond the standard model. Many models and mechanisms are proposed to explain their smallness naturally. Some of them generate tiny neutrino masses by the effect of very heavy particles (seesaw mechanism), and others generate them by quantum effect of new particles whose masses are near EW scale. However, it was shown that most of

I am going to discuss possibility of discovering dark matter particles at future e+e- colliders such as CLIC, ILC or CEPC.
Within several simple models, I will try to answer the following questions:
(1) Where, in the parameter space, is the region allowed by current experimental constraints, that maximizes
cross section for DM production at the colliders?
(2) Could the signal of DM be

One of the most rapidly developing areas of research in particle physics nowadays is to look for new, light, extremely weakly-interacting particles that could have escaped detection so far due to the lack of sufficient luminosity. A particularly promising experimental strategy in these, so-called, intensity-frontier searches is to look for highly-displaced decay signatures of light long-lived part

Motivated by the fact that so far all evidence for dark matter (DM) has gravitational origin, we explore the possibility that the dark sector is coupled to the standard model (SM) only gravitationally. We discuss two mechanisms that can contribute to the DM production - \textit{non-perturbative} and \textit{perturbative}. The first case refers to the particle production due to time evolution of th

We consider cases where the dark matter-nucleon interaction is naturally suppressed. We explicitly show that extending the standard model scalar sector by a number of singlets can lead to a vanishing direct detection cross section, if some softly broken symmetries are imposed in the dark sector. In particular, it is shown that if said symmetries are SU(2) [SU(N)] or U(1)×SN, then the resulting Ps
