Fast Neutron - Mirror Neutron Oscillation and Ultra High Energy Cosmic Rays
Zurab Berezhiani, Luis Bento
If there exists the mirror world, a parallel hidden sector of particles with exactly the same microphysics as that of the observable particles, then the primordial nucleosynthesis…
Neutron -- Mirror Neutron Oscillation: How Fast Might It Be?

This paper has been withdrawn by the authors to avoid redundancy with e-print hep-ph0507031.
Neutron - Mirror Neutron Oscillations: How Fast Might They Be?
Zurab Berezhiani, Luis Bento
We discuss the phenomenological implications of the neutron (n) oscillation into the mirror neutron (n'), a hypothetical particle exactly degenerate in mass with the neutron but st…
Sphaleron relaxation temperatures
Luis Bento
The transition of sphaleron processes from non-equilibrium to thermal equilibrium in the early Universe is examined in detail. The relations between the damping rates and frequenci…
Leptogenesis in a prompt decay scenario
Luis Bento
Leptogenesis is studied within the seesaw neutrino mass model in a regime where all sterile neutrinos have prompt rather than delayed decays. It is shown that during neutrino therm…
Baryogenesis: The Lepton Leaking Mechanism
Luis Bento, Zurab Berezhiani
We propose a baryo- and leptogenesis mechanism in which the B-L asymmetry is produced in the conversion of ordinary leptons into particles of some depleted hidden sector. In partic…
