Bounds on the light quark masses

High Energy Physics - Phenomenology 2009-10-28 v1

Abstract

The corrections to the current algebra mass formulae for the pseudoscalar mesons are analyzed by means of a simultaneous exansion in powers of the light quark masses and powers of 1/N. A set of mass formulae is derived, including an inequality, which leads to bounds for ratios of quark masses.
