Abstract
We present our preliminary result for the charmed quark mass, which follows from taking the D_s and K meson masses from experiment and r0=0.5 fm (or, equivalently F_K=160 MeV) to set the scale. For the renormalization group invariant quark mass we obtain M_c = 1684(64) MeV, which translates to m_c(m_c)= 1314 (40)(20)(7) MeV for the running mass in the MSbar scheme. Renormalization is treated non-perturbatively, and the continuum limit has been taken, so that the only uncontrolled systematic error consists in the use of the quenched approximation.
