A bstract We compute the decay spectrum for dark matter (DM) with masses above the scale
of electroweak symmetry breaking, all the way to the Planck scale. For an arbitrary hard …

A bstract Dark Matter could be a composite state of a confining sector with an approximate
scale symmetry. We consider the case where the associated pseudo-Goldstone boson, the …

We use HESS γ-ray observations of Sgr A* to derive novel limits on the Dark Matter (DM)
annihilation cross-section. We quantify their dependence on uncertainties i) in the DM halo …

The kilometer square array (KM2A) of the large high altitude air shower observatory
(LHAASO) aims at surveying the northern γ-ray sky at energies above 10 TeV with …

Dark matter (DM) as a thermal relic of the primordial plasma is increasingly pressured by
direct and indirect searches, while the same production mechanism in a decoupled sector is …

In this article we show that in the usual type-I seesaw framework, augmented solely by a
neutrino portal interaction, the dark matter (DM) relic density can be created through freeze …

We consider, in general terms, the possible parameter space of thermal dark matter
candidates. We assume that the dark matter particle is fundamental and was in thermal …

A massive particle decaying into neutrinos in the early Universe is known to be less
constrained than if it was decaying into other standard model particles. However, even if the …

Abstract In an earlier work [1], we showed that in very simple neutrino portal-like extensions
of the Standard Model it is possible to achieve a one-to-one correspondence between dark …

We consider a scenario in which the dark matter is alone in a hidden sector and consists of a
real scalar particle with a manifest or spontaneously broken Bbb Z 2 symmetry, at a …
