This report provides an extensive review of the experimental programme of direct detection
searches of particle dark matter. It focuses mostly on European efforts, both current and …

We review several current aspects of dark matter theory and experiment. We overview the
present experimental status, which includes current bounds and recent claims and hints of a …

We lay out a comprehensive physics case for a future high-energy muon collider, exploring
a range of collision energies (from 1 to 100 TeV) and luminosities. We highlight the …

We obtain a reliable cosmological bound on the axion mass ma by (1) deriving the
production rate directly from pion-pion scattering data, which overcomes the breakdown of …

We study the effects of long-lived massive particles, which decayed during the big-bang
nucleosynthesis (BBN) epoch, on the primordial abundance of light elements. Compared to …

We analyze in detail the perturbative decay of the inflaton oscillating about a generic form of
its potential V (ϕ)= ϕ k, taking into account the effects of non-instantaneous reheating. We …

Increasingly stringent limits from LHC searches for new physics, coupled with lack of
convincing signals of weakly interacting massive particle (WIMP) in dark matter searches …

Leptogenesis is a class of scenarios where the baryon asymmetry of the Universe is
produced from a lepton asymmetry generated in the decays of heavy singlet neutrinos. We …

In this review article, we discuss the current status and future prospects of perturbation
theory as a means of studying the equilibrium thermodynamic and near-equilibrium …

We investigate the power spectrum of Non-Cold Dark Matter (NCDM) produced in a state out
of thermal equilibrium. We consider dark matter production from the decay of scalar …
