Abstract
We study the shift in the mass due to a non-zero charm quark mass. This shift affects the value of the -quark mass extracted from the system by about -20 MeV, due to an incomplete cancellation of terms that are non-analytic in the charm quark mass. The precise size of the shift depends on unknown higher order corrections, and might have a considerable uncertainty if they are large.
