A Completely Invariant SUSY Transform of Supersymmetric QED | | M. L. Walker
; | | Date: |
10 Oct 2003 | | Journal: | J.Phys. G30 (2004) 1219-1224 | | Subject: | hep-th | | Abstract: | We study the SUSY breaking of the covariant gauge-fixing term in SUSY QED and observe that this corresponds to a breaking of the Lorentz gauge condition by SUSY. Reasoning by analogy with SUSY’s violation of the Wess-Zumino gauge, we argue that the SUSY transformation, already modified to preserve Wess-Zumino gauge, should be further modified by another gauge transformation which restores the Lorentz gauge condition. We derive this modification and use the resulting transformation to derive a Ward identitiy relating the photon and photino propagators without using ghost fields. Our transformation also fulfills the SUSY algebra, modulo terms that vanish in Lorentz gauge. | | Source: | arXiv, hep-th/0310098 | | Services: | Forum | Review | PDF | Favorites | |
