An analytical description for the cosmological constant
E. M. C. Abreu, C. M. L. dos Reis
From the principles of quantum cosmologies we can justify the reason for an inverse-square law for the cosmological constant with no conflict with observations. Although this gener…
Glueball and hybrid mass and decay with string tension below Casimir scaling
Elsa Abreu, Pedro Bicudo
Lattice computations with excited SU(3) representations suggest that the confining gluon-gluon interaction complies with the Casimir scaling. The constituent gluon models have also…
Effective Action for QED with Fermion Self-Interaction in D=2 and D=3 Dimensions
E. M. C. Abreu, D. Dalmazi, A. de Souza Dutra +1
In this work we discuss the effect of the quartic fermion self-interaction of Thirring type in QED in D=2 and D=3 dimensions. This is done through the computation of the effective…
The Jacobi identity for Dirac-like brackets
E. M. C. Abreu, D. Dalmazi, E. A. Silva
For redundant second-class constraints the Dirac brackets cannot be defined and new brackets must be introduced. We prove here that the Jacobi identity for the new brackets must ho…
ON THE COVARIANTIZATION OF THE CHIRAL CONSTRAINT
C. Neves, E. M. C. de Abreu, C. Wotzasek
We show that a complete covariantization of the chiral constraint in the Floreanini-Jackiw necessitates an infinite number of auxiliary Wess-Zumino fields otherwise the covariantiz…
