Electromagnetic Hadron Mass Differences and Estimation of Isotopic Symmetry Violation Parameters of QCD Vacuum from Quark Model

Technical Report:

Abstract

The estimations of the light quark mass differences, m{sub d} - m{sub u}, and the light quark condensate differences, - , are obtained in the framework of the quark model with QCD vacuum induced quark interaction. We consider long-wave condensate and short wave instanton contributions to the electromagnetic hadron mass differences and show that the latter significantly improve the results on baryon octet. The results are :M{sub d} - m{sub u} {approx} 3.5 MeV and - {approx} -(0{approx}) {center_dot} 10{sup -3} . (author). 37 refs.; 1 tab.
