We review scenarios in which the particles that account for the Dark Matter (DM) in the
Universe interact only through their couplings with the Higgs sector of the theory, the so …

We generalize models invoking a spin-2 particle as a mediator between the dark sector and
the standard model. We show that a massive spin-2 messenger can efficiently play the role …

We consider a dark matter scenario in the context of the minimal extension of the Standard
Model (SM) with a B− L (baryon number minus lepton number) gauge symmetry, where …

The neutron lifetime anomaly has been used to motivate the introduction of new physics with
hidden-sector particles coupled to baryon number, and on which neutron stars provide …

We study the freeze-in production of vector dark matter (DM) in a classically scale invariant
theory, where the Standard Model (SM) is augmented with an abelian U (1) X gauge …

A bstract We show that a minimal scenario, utilizing only the graviton as an intermediate
messenger between the inflaton, the dark sector and the Standard Model (SM), is able to …

We demonstrate that in a class of the U (1)′ extension of the Standard Model (SM), under
which all the Standard Model matter fields are uncharged and the additional neutral gauge …

A bstract Strongly Interacting Massive Particles (SIMPs) have recently been proposed as
light thermal dark matter relics. Here we consider an explicit realization of the SIMP …

Short-lived mediators are often used to describe dark matter interactions with Standard
Model particles. When the dark matter mass is heavier than the mass of the mediator, it may …

The apparent tensions emerging from the comparison of experimental data of the
anomalous magnetic moments of the muon and electron to the Standard Model predictions …
