Radiative 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 کاملHadronic Weak Decays of Hyperons in a Soliton Model
We study the parity violating hyperon non-leptonic weak decays in the three flavor Skyrme model. We follow the approach in which the symmetry breaking terms in the action are diagonalized exactly within the collective coordinate approximation. We show that although this method introduces some configuration mixing, the ∆I = 1/2 rule is numerically well satisfied. In addition, and in contrast to ...
متن کاملRadiative Weak Annihilation Decays
A class of meson decay modes sensitive to only one quark topology at leading GF order (annihilation of valence quarks through a W ) is described. No experimental observations, nor even upper limits, have been reported for these decays. This work presents a simpleminded (order-of-magnitude) calculation of their branching fractions, and compares to results of previous calculations where available...
متن کاملWeak Radiative Hyperon Decays
It is shown that an alternative form of the parity-nonconserving (PNC) transition electromagnetic current resolves partly a puzzle with the Hara theorem. New formulation of it has allowed PNC weak radiative hyperon transitions of the charged hyperons Σ+ ⇒ p + γ and Ξ ⇒ Σ + γ revealing hitherto unseen transition toroid dipole moment.
متن کاملWeak 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...
