Abstract

We update determination of the MS masses of the charm and bottom quarks, from comparisons of the masses of the charmonium and bottomonium 1. S states with their perturbative predictions up to next-to-next-to-next-to-leading order in ε expansion and using the MS masses. Effects of non-zero charm-quark mass in the bottomonium masses are incorporated up to next-to-next-to-leading order. We obtain mc=1246±2(d3)±4(αs)±23(h.o.) MeV and mb=4197±2(d3)±6(αs)±20(h.o.)±5(mc) MeV, which agree with the current Particle Data Group values.
