Description

Electromagnetic splitting of hadron masses have been calculated in a combined model taking account of the interaction with QCD vacuum condensates. Total mass difference is determined with the contribution sum: electromagnetic quark interaction, dependence of kinetic quark energy on their mass difference and with the effect of quark mass difference on strong interaction potential. It is shown that taking account of the quark interaction with QCD vacuum permits to satisfactorily describe experimental data. Difference of U and d quark masses: md-mu=3.7 MeV - has been estimated
