Determining the $\beta$-function of the strong interaction and closing the light gluino window
We discuss the perturbative running of alpha_s in a model independent way. Our analysis contains the data on the hadronic tau decay and all the total hadronic cross sections in e+e- annihilation between 5 GeV and M_Z. We determine the color coefficients and the perturbative beta-function of the stro...
