We incorporate chiral symmetry breaking in a soft-wall version of the AdS/QCD model by using a modified dilaton profile and a quartic term in the bulk scalar potential. This allows one to separate the dependence on spontaneous and explicit chiral symmetry breaking. The resulting mass spectra in the scalar, vector and axial-vector sectors compares favorably with the respective QCD resonances.

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