Matter and antimatter in the universe

Marco Drewes, Laurent Canetti

We review observational evidence for a matter-antimatter asymmetry in the early universe, which leads to the remnant matter density we observe today. We also discuss bounds on the presence of antimatter in the present-day universe, including the possibilit ...

Quantum leptogenesis I

Marco Drewes

Thermal leptogenesis explains the observed matter-antimatter asymmetry of the universe in terms of neutrino masses, consistent with neutrino oscillation experiments. We present a full quantum mechanical calculation of the generated lepton asymmetry based o ...

Dark energy with non-adiabatic sound speed: initial conditions and detectability

Julien Lesgourgues

Assuming that the universe contains a dark energy fluid with a constant linear equation of state and a constant sound speed, we study the prospects of detecting dark energy perturbations using CMB data from Planck, cross-correlated with galaxy distribution ...

Sterile neutrino dark matter as a consequence of nuMSM-induced lepton asymmetry

It has been pointed out by one of the authors (Shaposhnikov 2008Preprint0804.4542) that in the νMSM (Standard Model extended with three right-handed neutrinos with masses smaller than the electroweak scale), there is a corner in the parameter space where C ...

Flavor effects in thermal leptogenesis

Steve Blanchet

We review recent developments in leptogenesis on flavor effects. Their account discloses an important connection between the matter-antimatter asymmetry of the Universe and CP violation at low energies. Besides, they modify the upper bound on the neutrino ...
