Baryogenesis from mixed particle decays
L. Covi, E. Roulet
We consider the violating asymmetries produced in the decay of heavy particles, studying the effects of heavy particle mixing for arbitrary mass splittings. A considerable enh…
Kicked neutron stars and microlensing
Silvia Mollerach, Esteban Roulet
Due to the large kick velocities with which neutron stars are born in supernovae explosions, their spatial distribution is more extended than that of their progenitor stars. The la…
Preheating and vacuum metastability in Supersymmetry
A. Riotto, E. Roulet, I. Vilja
The constraints imposed by the requirement that the scalar potential of supersymmetric theories does not have unbounded directions and charge or color breaking minima deeper than t…
CP violating decays in leptogenesis scenarios
L. Covi, E. Roulet, F. Vissani
We compute the CP violation in the decays of heavy electroweak singlet neutrinos, arising from both the one--loop vertex corrections and the wave function mixing. We extend the com…
Microlensing
E. Roulet, S. Mollerach
Microlensing observations have now become a useful tool in searching for non--luminous astrophysical compact objects (brown dwarfs, faint stars, neutron stars, black holes and even…
