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

A. E. Dorokhov

The estimations of the light quark mass differences, $m_d-m_u$, and the light quark condensate differences, $<\bar{D}D>-<\bar{U}U>$, are obtained in the framework of the \qm\ with…
