Erratum to: A new quarkonium potential model

Summary

We propose a new quarkonium potential model as (C—(lnr/r ₀)⁻¹) GeV withC=−3.2,r ₀=3 fm. This model featuresa) Coulomb-like fall-off asr→0,b) extended linearity region, 0.03 fm <r<1.2 fm,c) natural confinement barrier atr=r ₀, andd) reproduction of charm and bottom quark masses to their real values by energy levels matching of the low-lying states.
