the Gliozzi-Scherk-Olive (GS0) projection [177]. An alternative light-cone gauge action with manifest spacetime supersymmetry was then proposed by Green and Schwarz [178] and shown by them to be equivalent (by virtue of the triality property of the Spin(8) transverse rotation group) to the light-con

yet to be found. Another issue which should be addressed is that of the representations content of the SU(212) symmetry uncovered for the superfiag Landau model [9], within the study of quantum mechanics on super manifolds. Preliminary results indicate these are new types of short representations previ

This fact can perhaps be understood most directly by recalling that the effective action is the generating functional for one- particle irreducible Green's functions, which themselves are gauge dependent [28]. In practice one often neglects this sub- tlety, fixes the gauge at the start of the calculat

lid varies with 41. We find that 14„r also changes at a level comparable to its sensitivity to Mg or Ali as the gauge pa- rameter deviates from the Landau gauge (egc = 0). It is there- fore important to consider this ambiguity for model building purposes. Nevertheless, the absolute change in lid is far
