Generators of Local Supersymmetry Transformation from First Class Constraints

We show how the generator of local supersymmetry transformations can be found from Fermionic first class constraints. This is done by adapting the approaches of Henneaux, Teit- elboim and Zanelli and of Castellani that has been used to find the generator of gauge trans- formations from Bosonic first class constraints. We illustrate how a supersymmetric gauge generator can be found by considering the spinning particle. The invariances that we find are not those presented in the original discussion of the spinning particle.Comment: nine page

A Gauge Theory that mixes Bosonic and Fermionic Gauge Fields

Using a gauge symmetry derived by applying the Dirac constraint formalism to supergravity with cosmological term in 2+1 dimensions, we construct a gauge theory with many characteristics of Yang-Mills theory. The gauge transformation mixes two Bosonic fields and one Fermionic field

The Renormalization Group and the Effective Potential in the Wess-Zumino model

We consider the effective potential V in the massless Wess-Zumino model. By using the renormalization group equation, we show that the explicit dependence of V on the renormalization mass scale mu cancels. If V has an extremum at some non-vanishing value of the background field, then it follows that V is "flat", independent of the background field. This is consistent with the general requirement that V be complex. The consequences for supersymmetric gauge theories are briefly considered

The Non-Abelian Gauge Field Propagator in a Plane Wave Background Field

Employing methods introduced by Schwinger in quantum electrodynamics, we compute the propagator for a non-Abelian gauge field in a plane wave background field. In the long distance limit a mass-like term for the gauge field is induced by this interaction
