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…

Barcelos-Wotzasek symplectic algorithm for constrained systems revisited

M. A. de Andrade, C. Neves, E. V. Corrêa Silva

A minor change in the Barcelos-Wotzasek (BW) symplectic algorithm for constrained systems is proposed. The change addresses some criticism that formalism has received, placing it o…

Noncommutative Derivation of the Planck's Radiation Law

M. A. De Andrade, L. G. Ferreira Filho, C. Neves

The Planck's radiation law for the blackbody radiation spectrum was capable to explain the experimentally-measured blackbody spectrum. In order to get this result, Planck proposed…

Noncommutative approach to disclose a Higgs group

M. A. De Andrade, C. Neves

A noncommutative(NC) version for a global scalar field theory is proposed and an alternative investigation about how noncommutative drives spontaneous symmetry breaking (SSB…

Noncommutative approach to diagnose degenerate Higgs bosons at 125 GeV

M. A. De Andrade, C. Neves

We propose a noncommutative (NC) version for a global O(2) scalar field theory, whose damping feature is introduced into the scalar field theory through the NC parameter. In this c…

A canonical transformation and the tunneling probability for the birth of an asymptotically DeSitter universe with dust

E. V. Corrêa Silva, G. A. Monerat, G. Oliveira-Neto +2

In the present work, we study the quantum cosmology description of closed Friedmann-Robertson-Walker models in the presence of a positive cosmological constant and a generic perfec…
