Massive Dirac neutrinos from a new extension of the Standard Model
M. A. De Andrade, C. Neves, E. V. Corrêa Silva
A new approach for deriving neutrino masses from the known masses of quarks, charged leptons, and the parameters of the Pontecorvo-Maki-Nakagawa-Sakata (PMNS) matrix is proposed. T…

Quantization of Friedmann-Robertson-Walker spacetimes in the presence of a negative cosmological constant and radiation
G. A. Monerat, E. V. Correa Silva, G. Oliveira-Neto +2
We quantize three Friedmann-Robertson-Walker models in the presence of a negative cosmological constant and radiation. The models differ from each other by the constant curvature o…
