Rhad: a program for the evaluation of the hadronic R-ratio in the perturbative regime of QCD
This paper describes the fortran program rhad which performs a numerical evaluation of the hadronic R-ratio, R(s), related to the cross section for electron-positron annihilation, for a given center-of-mass energy \sqrt{s}. In rhad the state-of-the-art perturbative corrections to R(s) are implemente...
