Abstract
An often used mass formula for Nambu-Goldstone (NG) bosons in QCD, such as the pions, involves the condensate , and the quark current masses. We argue, within the context of the Global Colour Model to QCD, that this expression is wrong. Analysis of the interplay between the Dyson-Schwinger equation for the constituent quark effect and the Bethe-Salpeter equation for the NG boson results in a new mass formula.
