A new estimate of the quark masses

Description

Assuming chiral symmetry breaking is due to a quark mass term, and some particular combinations of the lowest-lying meson states belong to the octet representation of the chiral algebra of the observable light plane charges, one finds for the bare quark masses the (approximate) formulae m(u)2 approximately equal to m(π)2/24, m(s)/m(u)=2m(k)F(k)/m(π)F(π)-1, leading to the numerical estimates m(u) approximately equal to 30MeV, m(s) approximately equal to 200MeV

Abstract (French)

En supposant que le brisement de la symetrie chirale est du a un terme de masse des quarks, et que certaines combinaisons particulieres des etats des mesons des basses energies appartiennent a la representation octet de l'algebre chirale des charges du genre lumiere (generees par les courants electromagnetique et faible des hadrons), on calcule les masses mecaniques des quarks et on trouve les formules: m(u)2 approximativement egal a m(u)2/24 (pour les quarks non etranges) et m(s)/m(u)=2m(k)F(k)/m(π)F(π)-1 pour le quark etrange, conduisant aux estimations numeriques m(u) approximativement egal a 30MeV et m(s) approximativement-egal-a 200MeV
