Hadronic Mass

Mass relations for hadrons containing a single heavy quark (charm or beauty) are studied from the viewpoint of a quark model with broken SU(8) symmetry, developed by Hendry and Lichtenberg some time ago, in comparison to that of the heavy quark effective theory. The interplay of the two approaches is explored and spectroscopic consequences derived.

Quark Theory

A constituent quark model is used to calculate the exclusive pair production of [Formula: see text] and [Formula: see text] mesons in e+e− annihilation. It allows one to illuminate the meaning of the 1/mb,c corrections to the leading order of the effective heavy quark theory.
