Two such d=6 operators have been considered. The present precision for measuring α_s implies a lower bound of around 2 Tev on the scale for the CP even operator O_1. On the other hand the precision for measuring d_n implies a lower bound of 10^5 TeV on the scale for the CP odd operator. We show that for the above lower bound O_1 can significantly affect the parton level cross-section for the process gg-->H.Plain Tex, no figsHigh Energy Physics - Phenomenologytext
