Radiative decays of baryons are considered in a field theoretic quark model of composite hadrons where the translationally invariant SU (6) hadron states are described by constituent quark field operators and harmonic oscillator wave functions. The constituent quark field operators of the model satisfying the equal time algebra are also Lorentz-boosted through a spin rotation to describe hadrons in motion. The model, like its earlier success in describing the different hadronic phenomena, in the present investigation without any free parameters, obtains the radiative decay widths and helicity amplitudes in reasonable agreement with other theoretical calculations as well as with the available experimental measurements.

We study the weak radiative decays of baryons when these are considered to be composed of baby Skyrmions. Weak interaction gauge bosons take a prominent role when a baby Skyrmion interacting with such a boson governs the main dynamics. This mechanism effectively gives rise to the pole model where the parity-conserving and parity-violating poles are not arbitrary but are dictated by the mechanism itself.

Decays Of Baryons

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.
