Abstract

We consider 1+11+1 dimensional Yang-Mills theory with gauge group GG coupled to a massive Majorana fermion field in an adjoint representation and a number of massless Dirac or Majorana fermions transforming in arbitrary representations of the gauge group GG. It is shown that the spectrum of the massive sector of this theory becomes supersymmetric at particular mass of adjoint fermion. This mass is independent of the detailed structure of the massless sector of the model and depends only on the gauge group GG and integer kk measuring the total anomaly. The massless sector of the model is shown to be not necessarily supersymmetric.
