Weak decays of τ-lepton and Λc+-baryon in the framework of phenomenological Lagrangians

In the framework of SU(3)·SU(3)-gauge theory the semilepton decays of τ-lepton were considered. The scheme of chiral symmetry breaking in the case of SU(4)·SU(4)-chiral group by means of accounting of additional angle of Lagrangian turning around of tenth axis of SU(4)-space was summarized. The description of τ-lepton decay with production of πη-mesons (generally bound with the existence of currents of II type) with the help of breaking scheme of SU(3)·SU(3)-chiral symmetry was given. Λc+-baryon decays (with the production of up to 4 hadrons in the final state) in SU(4)·SU(4)-gauge theory with taking into account of breaking of SU(4)·SU(4)-chiral symmetry were considered.
