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 Pătuleanu, 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 rot…
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…
Production of massive bosons and fermion-antifermion pairs from vacuum in the de Sitter Universe
Cosmin Crucean, Amalia Dariana Fodor
In this paper we study the charged electro-weak interactions in the de Sitter geometry. We develop the reduction formalism for the Proca field with the help of the solutions for th…
A perturbative production of massive Z bosons and fermion-antifermion pairs from the vacuum in the de Sitter Universe
Diana Dumitrele, Mihaela-Andreea Băloi, Cosmin Crucean
In this paper we study the problem of neutral electro-weak interactions in a de Sitter geometry. We develop the formalism of reduction for the Proca field with the help of the solu…
Z boson emission by a neutrino in de Sitter expanding universe
Mihaela-Andreea Baloi, Cosmin Crucean, Diana Dumitrele
Production of Z bosons in emission processes by neutrinos in the expanding de Sitter universe is studied by using perturbative methods. The total probability and transition rate fo…
