Fermion Scattering by Phase Boundaries
Andro Barnaveli, Merab Gogberashvili
We consider interactions of fermions with the domain wall bubbles produced during the first order phase transitions. New exact solution of Dirac equations and reflection coefficien…
Temperature Shift of Neutrino Energy in the External Magnetic Field
M. Gogberashvili, L. Midodashvili, P. Midodashvili
It is evaluated the first order temperature correction to the energy of massive neutrino in the case of weak magnetic field.
BARYON AND TIME ASYMMETRIES OF THE UNIVERSE
Andro Barnaveli, Merab Gogberashvili
This paper is devoted to the investigation of connection between two apparent asymmetries of the nature --- time-asymmetry and Baryon Asymmetry of the Universe (BAU). The brief rev…
ANTIGRAVITATING BUBBLES
Andro Barnaveli, Merab Gogberashvili
We investigate the gravitational behavior of spherical domain walls (bubbles) arising during the phase transitions in the early Universe. In the thin-wall approximation we show the…
