It is commonly assumed that the energy density of the Universe was dominated by radiation
between reheating after inflation and the onset of matter domination 54,000 years later …

Exotic decays of the Standard Model (SM)-like Higgs boson into beyond-the-SM particles
are predicted in a wide range of well-motivated theories. The enormous samples of Higgs …

The discovery of the Higgs boson in 2012, by the ATLAS and CMS experiments, was a
success achieved with only a percent of the entire dataset foreseen for the LHC. It opened a …

A bstract A model of vector dark matter that communicates with the Standard Model only
through gravitational interactions has been investigated. It has been shown in detail how …

We derive improved stellar luminosity limits on a generic light CP-even scalar field S mixing
with the Standard Model (SM) Higgs boson from the supernova SN1987A, the Sun, red …

Hawking evaporation of primordial black holes (PBH) with masses ranging from∼ 10-1 to∼
10 9 g can generate the whole observed dark matter (DM) relic density. However, a second …

Abstract Weakly-and Feebly-Interacting Massive Particles (WIMPs and FIMPs) are among
the best-motivated dark matter (DM) candidates. In this paper, we investigate the production …

A notable feature of UV freeze-in is that the relic density is strongly dependent on the highest
temperatures of the thermal bath, and a common assumption is that the relevant" highest …

We study the impact of thermalization and number-changing processes in the dark sector on
the yield of gravitationally produced dark matter (DM). We take into account the DM …

We explore the production of thermal dark matter (DM) candidates (WIMPs, SIMPs, ELDERs
and Cannibals) during cosmic reheating. Assuming a general parametrization for the scaling …
