Nilpotent Symmetry Invariance In Superfield Formalism: 1-Form
(Non-)Abelian Gauge Theories | R. P. Malik
; | Date: |
1 Apr 2007 | Subject: | hep-th (High Energy Physics - Theory) | Abstract: | We capture the well-known off-shell as well as the on-shell nilpotent
Becchi-Rouet-Stora-Tyutin (BRST) and anti-BRST symmetry transformations for the
Lagrangian densities of the four (3 + 1)-dimensional (4D) 1-form (non-)Abelian
gauge theories within the framework of the superfield formalism. In particular,
we provide the geometrical interpretations for (i) the above nilpotent symmetry
invariance(s), and (ii) the Lagrangian densities of the theories, within the
framework of the superfield approach to BRST formalism. Some of the subtle
points, connected with the 4D (non-)Abelian 1-form gauge theories, are
clarified within the above superfield approach where the 4D ordinary gauge
theories are considered on the (4, 2)-dimensional supermanifold parametrized by
the four spacetime coordinates x^mu (with mu = 0, 1, 2, 3) and a pair of
Grassmannian variables heta and ar heta. One of the key results of our
present investigation is a great deal of simplification in the understanding of
the nilpotent (anti-)BRST symmetry invariance(s) of the present 4D 1-form
(non-)Abelian gauge theories. | Source: | arXiv, arxiv.0704.0064 | Services: | Forum | Review | PDF | Favorites |
