The Charm Quarks's Mass

The charm quark’s mass is determined from Monte Carlo calculations of the $\bar{c}c$ spectrum. The main sources of uncertainty are perturbation theory (for conversion to $\text{MSbar}$), the continuum-limit extrapolation, Monte Carlo statistics, and the effects of quenching. The (preliminary) result for the $\text{MSbar}$ mass is ${\bar{m}}_{ch}(m_{ch})=1.33\pm 0.08$ GeV.
