N = 2 Super Yang-mills Action as a Becchi-rouet-stora-tyutin Term, Topological Yang-mills Action and Instantons
By constructing a nilpotent extended BRST operator ¯ s that involves the N=2 global supersymmetry transformations of one chirality, we show that the standard N=2 off-shell Super Yang Mills Action can be represented as an exact BRST term ¯ sΨ, if the gauge fermion Ψ is allowed to depend on the inverse powers of supersymmetry ghosts. By using this nonanalytical structure of the gauge fermion (via...
متن کاملBecchi-Rouet-Stora-Tyutin treatment of collective coordinates.
The Becchi-Rouet-Stora-Tyutin (BRST) treatment for the quantization of collective coordinates is considered in the Lagrangian formalism. The motion of a particle in a Riemannian manifold is studied in the case when the classical solutions break a non-abelian global invariance of the action. Collective coordinates are introduced, and the resulting gauge theory is quantized in the BRST antifield ...
متن کاملBRST - invariant composite operator of mass dimension 2 in Yang - Mills theory
We discuss the renormalization of a BRST and anti-BRST invariant composite operator of mass dimension 2 in Yang-Mills theory with the general BRST and anti-BRST invariant gauge fixing term of the Lorentz type. The interest of this study stems from a recent claim that the non-vanishing vacuum condensate of the composite operator in question can be an origin of mass gap and quark confinement in a...
متن کاملBecchi-Rouet-Stora-Tyutin quantization of a soliton model in 2+1 dimensions.
The Becchi-Rouet-Stora-Tyutin (BRST) method is applied to the quantization of the solitons of the non-linear O(3) model in 2+1 dimensions. We show that this method allows for a simple and systematic treatment of zero-modes with a non-commuting algebra. We obtain the expression of the BRST hamiltonian and show that the residual interaction can be perturbatively treated in an IR-divergence-free w...
متن کاملThe anomalous dimension of the gluon-ghost mass operator in Yang-Mills theory
The local composite gluon-ghost operator ( 1 2 AA μ + αcc ) is analysed in the framework of the algebraic renormalization in SU(N) Yang-Mills theories in the Landau, CurciFerrari and maximal abelian gauges. We show, to all orders of perturbation theory, that this operator is multiplicatively renormalizable. Furthermore, its anomalous dimension is not an independent parameter of the theory, bein...
