Abstract

We estimate the presently unknown constant in the 4-loop relation between the quark pole mass and the MS mass, by requiring stability of the perturbative prediction for E_tot(r) = 2m_pole + V_QCD(r) in the intermediate-distance region. The estimate is fairly sharp due to a severe cancellation between 2m_pole and V_QCD(r). This would provide a test, based on general properties of the gauge theory, for the size of ultra-soft contributions to V_QCD(r)
