AbstractAbstract
[en] A nonlinear realization of the SU(2)sub(L)xU(1) gauge group has been constructed using a chiral SU(4)xSU(4) lagrangian of hadrons. Weak and electromagnetic interactions of O- mesons and 1/2+ baryons are described. The effective lagrangian obtained for the weak interaction of hadrons has the usual current x current structure. Charmed charged currents are of the Cabibbo type, the neutral current satisfies the ΔS=0 condition of the GIM-scheme. Semileptonic and leptonic decays of D- and F-mesons are calculated
