Calculations of deep inelastic processes (DIS) to next-to-next to leading
order are discussed. Fitting $ep$ experiment in the range $2.5\leq Q^2\leq 230
GeV^2$, we find the coupling $\alpha_s(M_Z^2)=0.1163\pm0.0023$. We also get the
gluon density $xG(x,Q^2\simeq 10 GeV^2)=0.51 x^{-0.44}(1-x)^{8.1}$, and
negative evidence for the existence of light gluinos
