Sharing but not caring: dark matter and the baryon asymmetry of the universe
(Iop Publishing Ltd, 2016-09-01)
We consider scenarios where Dark Matter (DM) particles carry baryon and/or lepton numbers, which can be defined if there exist operators connecting the dark to the visible sector. As a result, the DM fields become intimately ...
On baryogenesis from dark matter annihilation
(Iop Publishing Ltd, 2013-10-01)
We study in detail the conditions to generate the baryon asymmetry of the universe from the annihilation of dark matter. This scenario requires a low energy mechanism for thermal baryogenesis, hence we first discuss some ...

Leptogenesis via hypermagnetic fields and baryon asymmetry
(IOP PUBLISHING LTDBRISTOL, 2012)
We study baryon asymmetry generation originated from the leptogenesis in the presence of hypermagnetic fields in the early Universe plasma before the electroweak phase I ransition (EWPT). For the simplest Chern-Simons (CS) ...
Lower bound on the electroweak wall velocity from hydrodynamic instability
(Iop Publishing, 2015-03)
The subsonic expansion of bubbles in a strongly first-order electroweak phase transition is a convenient scenario for electroweak baryogenesis. For most extensions of the Standard Model, stationary subsonic solutions (i.e., ...
The impact of particle production on gravitational baryogenesis
(2016-11-10)
Baryogenesis driven by curvature effects is investigated by taking into account gravitationally induced particle production in the very early Universe. In our scenario, the baryon asymmetry is generated dynamically during ...
