Hamiltonian embedding of the massive Yang-Mills theory and the generalized Stückelberg formalism
نویسنده
چکیده
Using the general notions of Batalin, Fradkin, Fradkina and Tyutin to convert second class systems into first class ones, we present a gauge invariant formulation of the massive Yang-Mills theory by embedding it in an extended phase space. The infinite set of correction terms necessary for obtaining the involutive constraints and Hamiltonian is explicitly computed and expressed in a closed form. It is also shown that the extra fields introduced in the correction terms are exactly identified with the auxiliary scalars used in the generalized Stückelberg formalism for converting a gauge noninvariant Lagrangian into a gauge invariant form. PACS: 11.10.Ef, 11.15.-q

Hamilton-Jacobi formalism of the massive Yang-Mills theory revisited
Using Hamilton-Jacobi formalism we investigated the massive Yang-Mills theory on both extended and reduced phase-space. The integrability conditions were discussed and the actions were calculated.
متن کاملPeriods and Prepotential of N=2 SU(2) Supersymmetric Yang-Mills Theory with Massive Hypermultiplets
We derive a simple formula for the periods associated with the low energy effective action of N = 2 supersymmetric SU(2) Yang-Mills theory with massive Nf ≤ 3 hypermultiplets. This is given by evaluating explicitly the integral associated to the elliptic curve using various identities of hypergeometric functions. Following this formalism, we can calculate the prepotential with massive hypermult...
متن کاملUnconstrained Hamiltonian Formulation of SU(2) Gluodynamics
One of the main issues in the Hamiltonian formulation of Yang-Mills theories is to find the projection from the phase space of canonical variables constrained by the non-Abelian Gauss law to the “smaller” phase space of unconstrained gauge invariant coordinates only. Dealing with the problem of the elimination of the pure gauge degrees of freedom two approaches exist, the perturbative and the n...
متن کاملEinstein-Yang-Mills-Maxwell-Inflaton System: I. Initial Value Problem
The general hamiltonian formalism for time-dependent EinsteinYang-Mills equations is presented and then applied to the well studied case of spherically symmetric su(2)−valued Yang-Mills fields. Here, we focus on by far less known time dependent solutions of these equations, and especially on perturbations of Friedmann-Lemaitre homogeneous solutions. By analysing the hamiltonian constraints, we ...
متن کاملAn Introduction to Generalized Yang-Mills Theories
In generalized Yang-Mills theories scalar fields can be gauged just as vector fields in a usual Yang-Mills theory, albeit it is done in the spinorial representation. The presentation of these theories is aesthetic in the following sense: A physical theory using Yang-Mills theories requires several terms and irreducible representations, but with generalized Yang-Mills theories, only two terms an...
