Heavy Meson Spectroscopy

Abstract

I n this article we give a review of certain aspects of the present understanding of spectroscopy of heavy mesons and constituent quark masses in the light of non-relativistic potential model approach motivated by quantum chromodynamics. We find that the one gluon exchange a t short distance and colour-confining interaction a t large distance which is pure scalar (or scalarvector admixture with dominant scalar interaction) under the Lorente transformation, can explain only partially the present data on 1P states of cE and bb states. The S-wave data, that are available a t present, however can be understood with both scalar confinement or scalar-vector admixture with scalar-dominant interaction.
