Mass sum rules for heavy-flavored hadrons.

Abstract

Regularities in hadron interaction energies are used to obtain formulas relating the masses of ground-state hadrons, most of which contain heavy quarks. Inputs are the constituent quark model, the Feynman-Hellmann theorem, and the structure of the color magnetic interaction of QCD. Some of the formulas can also be obtained from heavy quark effective theory or from hadron supersymmetry. Where data exist, the formulas agree quite well with experiment, but most of the sum rules provide predictions of heavy baryon masses that will be useful for future measurements.
