Early Universe production of bosons in neutrino decays
Amalia Dariana Fodor, Andru Mihai Buga, Cosmin Crucean
In this paper we study, via perturbative methods, the rates of production of bosons emitted in neutrino decays during the early stages of the Universe. We compute the transitio…

Dirac fermions under imaginary rotation
Tudor PÄtuleanu, Amalia Dariana Fodor, Victor E. Ambrus +1
In the present study, we investigate the properties of an ensemble of free Dirac fermions, at finite inverse temperature and finite chemical potential , undergoing rigid r…

Emission of bosons by electrons and decays of bosons in the early universe
Amalia Dariana Fodor, Cosmin Crucean
In this paper we study the transition rates for the decay of bosons into leptons in de Sitter spacetime. From the results obtained in the de Sitter geometry we recover th…
