摘要：

Global supersymmetry (SUSY) in supersymmetric gauge theory is generally broken by gauge fixing. A prescription to extract physical information from such SUSY algebra broken by gauge fixing is analyzed in the path integral framework. If delta(SUSY)delta(BRST)Psi = delta(BRST)delta(SUSY)Psi for a gauge fixing "fermion" Psi, the SUSY charge density is written as a sum of the piece which is naively expected without gauge fixing and a BRST exact piece. If delta(SUSY)delta(SUSY)delta(BRST)Psi = delta(BRST)delta(SUSY)delta(SUSY)Psi, the equal-time anti-commutator of SUSY charge is written as a sum of a physical piece and a BRST exact piece. We illustrate these properties for N = 1 and N = 2 supersymmetric Yang-Mills theories and for a D = 10 massive superparticle (or "D-particle") where the kappa-symmetry provides extra complications.
