Abstract
We report on the analytical calculation of NNNLO(O(alpha(s)(3))) conversati on factor between the <(MS)over bar> quark mass and the one defined in the and in the so-called "Regularization Invariant" scheme. The NNNLO contribut ion in tile conversion factor turns out to be relatively large and comparab lc to the known NNLO term.
