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 …

The discovery of the Higgs boson has opened a new avenue for exploring physics beyond
the Standard Model. In this review, we discuss cosmological aspects of the simplest Higgs …

Classically conformal Standard Model extensions predict an intriguing thermal history of the
early Universe. In contrast to the common paradigm, the onset of the electroweak phase …

A bstract We explore the possibility that the fundamental theory of nature does not contain
any scale. This implies a renormalizable quantum gravity theory where the graviton kinetic …

A bstract We present an updated analysis of the first-order phase transition associated with
symmetry breaking in the early Universe in a classically scale-invariant model extended with …

A rather minimal possibility is that dark matter consists of the gauge bosons of a
spontaneously broken symmetry. Here we explore the possibility of detecting the …

A bstract In this paper we investigate the phenomenology of a very light scalar, h, with mass
100 MeV< mh< 10 GeV, mixing with the SM Higgs. As a benchmark model we take the real …

We study the standard model (SM) in its full perturbative validity range between Λ QCD and
the U (1) Y Landau pole, assuming that a yet unknown gravitational theory in the UV does …

A bstract Theories where the Planck scale is dynamically generated from dimensionless
interactions provide predictive inflationary potentials and super-Planckian field variations …

We consider a classically scale invariant version of the Standard Model, extended by an
extra dark SU (2) X gauge group. Apart from the dark gauge bosons and a dark scalar …
