Supersymmetry in QCD$_2$ coupled to fermions
We consider $1+1$ dimensional Yang-Mills theory with gauge group $G$ 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 $G$. It is shown that the spectrum of the mas...

| Abstract | We consider $1+1$ dimensional Yang-Mills theory with gauge group $G$ 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 $G$. 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 $G$ and
integer $k$ measuring the total anomaly. The massless sector of the model is
shown to be not necessarily supersymmetric. |
