Abstract:
The paper considers $N=1$ supersymmetric Yang–Mills theories in dimensions $d=4$
and $d=6$ on the light cone. The $N=2$ theory in $d=4$ is obtained by dimensional
reduction. The results are represented in the superfield formulation of Mandelstam.
Feynman rules for the superfields are obtained. The well-known fact is confirmed
that the $N=2$ theory in $d=4$ has only single-loop divergences in the gauge considered.
