Note on an extended chiral bosons system contextualized in a modified gauge-unfixing formalism
Gabriella V. Ambrosio, Cleber N. Costa, Paulo R. F. Alves +2
We analyze the Hamiltonian structure of an extended chiral bosons theory in which the self-dual constraint is introduced via a control -parameter. The system has two second-clas…
Modified gauge unfixing formalism and gauge symmetries in the non-commutative chiral bosons theory
Cleber N. Costa, Gabriella V. Ambrósio, Paulo R. F. Alves +2
We use the gauge unfixing (GU) formalism framework in a two dimensional noncommutative chiral bosons (NCCB) model to disclose new hidden symmetries. That amounts to converting a se…
Gauge Symmetry of the Chiral Schwinger model from an improved Gauge Unfixing formalism
Gabriella V. Ambrosio, Cleber N. Costa, Paulo R. F. Alves +3
In this paper, the Hamiltonian structure of the bosonized chiral Schwinger model (BCSM) is analyzed. From the consistency condition of the constraints obtained from the Dirac metho…
Restoring the gauge invariance in non-Abelian second-class theories
Paulo R. F. Alves, Cleber N. Costa, D. Fiorentini +3
In this paper, we propose a generalization of an improved gauge unfixing formalism in order to generate gauge symmetries in the non-Abelian valued systems. This generalization disp…
Revealing hidden symmetries and gauge invariance of the massive Carroll-Field-Jackiw model
Paulo R. F. Alves, Cleber N. Costa, Everton M. C. Abreu +2
In this paper we have analyzed the improved version of the Gauge Unfixing (GU) formalism of the massive Carroll-Field-Jackiw model, which breaks both the Lorentz and gauge invarian…
