Abstract:
Certain two and three point functions of gauge invariant primary operators of N=4{\cal N}=4 SYM are computed in N=1{\cal N}=1 superspace keeping all the th\th-components. This allows one to read off many component descendent correlators. Our results show the only possible gYM2g^2_{YM} corrections to the free field correlators are contact terms. Therefore they vanish for operators at separate points, verifying the known non-renormalization theorems. This also implies the results are consistent with N=4{\cal N}=4 supersymmetry even though the Lagrangian we use has only N=1{\cal N}=1 manifest supersymmetry. We repeat some of the calculations using supersymmetric Landau gauge and obtain, as expected, the same results as those of supersymmetric Feynman gauge.
