Weak Radiative Decays of Hyperons and of Charm and Beauty Baryons *
A review is presented of the weak radiative decays of baryons. It includes an analysis of the possible contributions of electromagnetic penguins to these decays, a survey of the difficulties still encountered in the sector of hyperon decays and a short account on some new developments on this topic. The theoretical treatments on charm and beauty baryon decays are summarized, with a good outlook...
متن کاملCabibbo-allowed nonleptonic weak decays of charmed baryons.
Cabibbo-allowed nonleptonic weak decays of charmed baryons Λ + c , Ξ 0A c , Ξ +A c and Ω 0 c into an octet baryon and a pseudoscalar meson are analyzed. The nonfactorizable contributions are evaluated under pole approximation, and it turns out that the s-wave amplitudes are dominated by the low-lying 2 − resonances, while pwave ones governed by the ground-state 2 + poles. The MIT bag model is e...
متن کاملSpectroscopy and Strong Decays of Charmed Baryons
In the past years many new excited charmed baryon states have been discovered by BaBar, Belle and CLEO. In particular, B factories have provided a very rich source of charmed baryons both from B decays and from the continuum ee → cc̄. A new era for the charmed baryon spectroscopy is opened by the rich mass spectrum and the relatively narrow widths of the excited states. Experimentally and theore...
متن کاملRadiative decays of decuplet hyperons
We calculate the radiative decay widths of decuplet hyperons in a chiral constituent quark model including electromagnetic exchange currents between quarks. Exchange currents contribute significantly to the E2 transition amplitude, while they largely cancel for the M1 transition amplitude. Strangeness suppression of the radiative hyperon decays is found to be weakened by exchange currents. Diff...
متن کاملQuark and pole models of nonleptonic decays of charmed baryons.
Quark and pole models of nonleptonic decays of charmed baryons are analysed from the point of view of their symmetry properties. The symmetry structure of the parity conserving amplitudes that corresponds to the contribution of the ground-state intermediate baryons is shown to differ from the one hitherto employed in the symmetry approach. It is pointed out that the ”subtraction” of sea quark e...
