TTP - TTP99-39 alpha_s^3 conversion relation between MS-bar and Euclidean quark masses

Institute for Theoretical Particle Physics (TTP)

We report on the analytical calculation of NNNLO (of order alpha_s^3) conversion factor between the MS-bar quark mass and the one defined in the so-called Regularization Invariant scheme. The NNNLO contribution in the conversion factor turns out to be relatively large and comparable to the known NNLO term.
