Abstract: We study one loop corrections to N=frac{1}{2}$ supersymmetric gauge theory. We calculate explicitly the three and four-1PI functions of the theory up to one loop corrections. We show that N =1/2 supersymmetric gauge theory is renormalisable at one loop using a standard method of renormalisation if one adds new term to lagrangian in order to cancel anomaly terms which appears in the three point functions.
