We present an overview of scenarios where the observed Dark Matter (DM) abundance
consists of Feebly Interacting Massive Particles (FIMPs), produced nonthermally by the so …

Despite its continued observational successes, there is a persistent (and growing) interest in
extending cosmology beyond the standard model, Λ CDM. This is motivated by a range of …

The existence of nonzero neutrino masses points to the likely existence of multiple Standard
Model neutral fermions. When such states are heavy enough that they cannot be produced …

Weak galaxy lensing surveys have consistently reported a lower amplitude for the matter
fluctuation spectrum, as measured by the S 8 parameter, than expected in the ΛCDM …

The Lyman-α forest 1D flux power spectrum is a powerful probe of several cosmological
parameters. Assuming a ΛCDM cosmology including massive neutrinos, we find that the …

This paper describes the physics case for a new fixed target facility at CERN SPS. The SHiP
(search for hidden particles) experiment is intended to hunt for new physics in the largely …

Searches for dark matter decaying into photons constrain its lifetime to be many orders of
magnitude larger than the age of the Universe. A corollary statement is that the abundance …

We present updated constraints on the free-streaming of warm dark matter (WDM) particles
derived from an analysis of the Lyman-α flux power spectrum measured from high-resolution …

Neutrinos, being the only fermions in the Standard Model of Particle Physics that do not
possess electromagnetic or color charges, have the unique opportunity to communicate with …

We show that dissipationless Λ cold dark matter simulations predict that the majority of the
most massive subhaloes of the Milky Way are too dense to host any of its bright satellites …
