A pure dirac's method for yang-mills expressed AS a constrained bf-like theory Article uri icon

abstract

  • A pure Dirac%27s method of Yang-Mills expressed as a constrained BF-like theory is performed. In this paper we study an action principle com- posed by the coupling of two topological BF-like theories, which at the La- grangian level reproduces Yang-Mills equations. By a pure Dirac%27s method we mean that we consider all the variables that occur in the Lagrangian density as dynamical variables and not only those ones that involve temporal derivatives. The analysis in the complete phase space enable us to calculate the extended Hamiltonian, the extended action, the constraint algebra, the gauge transfor- mations and then we carry out the counting of degrees of freedom. We show that the constrained BF-like theory correspond at classical level to Yang-Mills theory. From the results obtained, we discuss briefly the quantization of the theory. In addition we compare our results with alternatives models that have been reported in the literature. © 2012 Academic Publications, Ltd.
