Özet

The relation between BRST cohomology and the N=1 supersymmetric Yang-Mills action in four dimensions is discussed. In particular, it is shown that both off- and on-shell N=1 SYM actions are related to a lower-dimensional field polynomial by solving the descent equations, which is obtained from the cohomological analysis of linearized Slavnov-Taylor operator B, in the framework of algebraic renormalization. Furthermore we show that off- and on-shell solutions differ only by a B-exact term, which is a consequence of the fact that the cohomology of both cases are the same.
