Description
The meaning and the extraction of heavy quark masses are discussed. A simple production model is presented which incorporates the running of the heavy quark mass into perturbative calculations. The model offers the possibilities of (i) understanding the differing charmed mass values extracted from different experiments, (ii) determining the short--distance mass relevent to quark mass matrix and mixing angle studies, and (iii) determining the long--distance charm mass, which determines the charm quark threshold and sensitively affects the extraction of $\sin^2θ_w $. Threshold and forward angle production offer the best possibilities to test the model and extract meaningful charm/bottom masses.
