Abstract
We analyze the contribution of scalars to the operator product expansion series for Maximum Helicity Violating (MHV) gluon scattering amplitudes/polygonal Wilson loops in planar supersymmetric Yang-Mills (SYM). Hence, we sum up on for large coupling : the logarithm of the amplitude is proportional to , thus competing, unexpectedly, with the famous classical contribution. We also give explicit expressions for the first terms at large . For this analysis, we find an explicit computation of the -scalar term at any coupling by means of Young tableaux, similar to Nekrasov-Okounkov expressions in SYM.
