VACUUM-STRUCTURE, CHIRAL-SYMMETRY BREAKING AND RADIATIVE DECAYS OF BARYONS

Radiative decays of baryons are considered in a model involving chiral symmetry breaking through a nontrivial vacuum structure. Pion and kao n, being treated consistently within the model, yield to the constitue nt quark wave functions approximately in the same way as the wave func tions from the gap equations, and thus in a way determine the constitu ent quark field operators. The model had a reasonable success earlier in its applications to some low energy hadronic phenomena, and here al so estimates radiative decay widths of baryons in reasonable agreement with other theoretical calculations as well as the available experime ntal measurements.
