A large number of Cosmic Microwave Background (CMB) polarization experiments have been searching for the CMB B-mode polarization signatures, which were produced either in degree scales by primordial gravitational waves from the epoch of cosmic inflation or in sub-degree scales by gravitational lensing by cosmological large-scale structure. POLARBEAR is a ground-based experiment designed to...

To interpret DE as the potential energy of the approximate U(1) dark energy
global symmetry, one must find color-anomaly free U(1). This necessarily
invites to consider U(1)de symmetry together with U(1)PQ symmetry such
that one gluon-anomaly free combination is constructed. This gives a hilltop
potential of height GUT scale energy density. Since the recent BICEP2
result forbid the...

We propose a ultraviolet complete theory for cold dark matter(CDM) and sterile neutrino that can accommodate both cosmological data and neutrino oscillation experiments at 1σ level. A new U(1)X dark gauge symmetry is introduced, and is assumed to be broken at ∼(MeV) scale. Such a light mediator for DM's self-scattering and scattering-off sterile neutrinos can resolve three controversies for...

We postulate that the need of transplanckian masses that single field inflation seems to need to accomodate experimental data can be due to the fact that we "force" our scalar field to be minimally coupled to gravity. Although it is true that the field itself is a "dummy" variable and one is always free to make a field redefinition to the Einstein frame (where the field is minimally coupled)...

We will start with a brief overview of ways to explain the similarity between the energy content of baryons and dark matter in the Universe. Then we will focus on scenarios of baryogenesis from dark matter annihilation, outlining the main ingredients. Finally we will present a variation of these mechanisms that brings a connection between the baryon asymmetry, dark matter, and neutrino masses.

Flavour effects play an important role in the statistical evolution of particle number densities. We present a fully flavour-covariant formulation of transport phenomena.

Despite the observational evidences in favor of Dark Matter its nature is still a mystery. Theoretical realizations assume that dark matter is stable and is the lightest state within the dark sector (e.g. WIMPs). The dark sector can also contains even lighter states like dark bosons and fermions. However, those can be completely disconnected from the visible sector except by interaction with...

It has been shown that the self-interaction between dark matter (DM) particles can increase the DM number density inside the Sun. The increasing rate of DM number density by this effect is proportional to the existing DM number density inside the Sun. We demonstrate that this effect can counteract DM evaporations in the regime of small DM mass. Consequently, the critical mass for DM...

The dark matter relic density has been measured by PLANCK and its predecessors with an accuracy of about 2%. We present theoretical calculations with DM@NLO in NLO SUSY QCD and beyond, which allow to reach this precision for gaugino and squark (co-)annihilations, and use them to scan the phenomenological MSSM for viable regions, applying also low-energy, electroweak and hadron collider constraints.

The halo independent comparison of direct dark matter detection data eliminates the need to make any assumption on the uncertain local dark matter distribution and is complementary to the usual data comparison which required assuming a dark halo model for our galaxy.
