The latest Planck CMB data seem to strongly constrain the Hot Dark Matter scenarios, although they stay in tension with direct Hubble constant measurements. However, one can believe that in near future the experimental uncertainly for the effective number of neutrino species N_{eff} will shrink vastly. Therefore, in order to estimate the allowed parameter space of models predicting a Hot Dark Matt

The choice of initial conditions in multifield inflation has a direct effect on observable quantities. Even after the attractor solution has been reached, the existence of multiple scalar degrees of freedom requires us to exclude certain inflationary trajectories when comparing their predictions to actual values. In the presence of observational uncertainties, this translates to fine-tuning for th

The absence of confirmed signal in dark matter (DM) direct detection (DD) may suggest a weak coupling between DM and the first generation quarks. In this work we consider a real scalar dark matter $S$ which has new Yukawa interactions with charm $c$ and top quark $t$ via a vector-like fermion mediator $\psi$. By setting the Higgs portal to be negligible, we focus on the new Yukawa interactions. Si

Minimal scenarios with light (sub-GeV) dark matter whose relic density is obtained from thermal freeze-out must include new light mediators. In particular, a very well-motivated case is that of a new "dark" massive vector gauge boson mediator. The mass term for such mediator is most naturally obtained by a "dark Higgs mechanism" which leads to the presence of an often long-lived dark Higgs boson w

It is possible that dark matter consists of two or more particle species with non-negligible contribution to the relic abundance. This scenario leads to a complicated dynamic in the hidden sector where various processes are responsible for the thermal production of dark matter. We discuss the model with fermionic and vector dark matter candidates that interact with the Standard Model through the H

In the framework of the $B-L$ Supersymmetric Standard Model (BLSSM), we assess the ability of ground and space based experiments to establish the nature of its prevalent Dark Matter (DM) candidate, the sneutrino, which could either be CP-even or -odd. Firstly, by benchmarking this theory construct against the results obtained by the Planck spacecraft, we extract the portions of the BLSSM parameter

We study a vector dark matter (VDM) model in which the VDM couples to the Standard Model sector via the Higgs portal. As a result, the VDM can be produced via the freeze-in mechanism. In particular, we find that the electroweak phase transition have a great impact on the prediction of the VDM relic density. We further assume that the dark Higgs which gives the VDM mass is so light that it can indu
