Decays Of Baryons

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.

The One

The chiral constituent quark model (χCQM) with general parametrization method (GPM) has been extended to calculate the charge radii of the charmed spin [Formula: see text] and spin [Formula: see text] baryons. The implications of such a model have been investigated for the effects of symmetry breaking and GPM parameters pertaining to the one-, two- and three-quark contributions. It is found that the χCQM along with these effects is successful in giving a quantitative and qualitative description of the charge radii of charmed baryons. In particular, it is able to account for the nonzero values of charge radii for the neutral charmed baryons.
