Аннотация:

The Domain Model of QCD vacuum and hadronisation is the mean-field approach based on the statistical ensemble of almost everywhere homogeneous Abelian (anti-)self-dual gluon fields. The model allows to deduce the effective meson action, which incorporates electroweak interactions. Using this meson action, the leptonic decay constants, form factors, and branching ratios of semileptonic decays are evaluated simultaneously with masses of mesons. The results are compared to experimental data or other approaches.
