Abstract

We consider the discretized version of the sigma-model with supersphere target space OSp(N+2m2m)/OSp(N+2m12m)OSp(N+2m|2m)/OSp(N+2m-1|2m) and present a preliminary numerical study of bosonic and fermionic two-point functions for the cases OSp(32)OSp(3|2) and OSp(52)OSp(5|2). We observe consistency with the expectations of this supersymmetric setup and discuss the sign problem.
