Weak Radiative Hyperon Decays
نویسنده
چکیده
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.

Alternative Form of the Parity-Violating Current for the Hyperon Weak Radiative Decays and Hara Theorem
It is shown that upon considering an alternative form of a parity-violating part of the transition electromagnetic current it is possible to reformulate Hara theorem in a way that it does not forbid any more nonzero asymmetry in the hyperon weak radiative decays Σ+ → p + γ and Ξ− → Σ− + γ in the limit of exact SU(3)f symmetry thus resolving a contradiction with the data and maybe revealing hith...
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...
متن کاملHyperon weak radiative decays in chiral perturbation theory.
We investigate the leading-order amplitudes for weak radiative decays of hyperons in chiral perturbation theory. We consistently include contributions from the next-to-leading order weak-interaction Lagrangian. It is shown that due to these terms Hara’s theorem is violated. The data for the decays of charged hyperons can be easily accounted for. However, at this order in the chiral expansion, t...
متن کاملWeak hyperon decays: Quark sea and SU(3) symmetry breaking.
An explanation of the difference in the values of the apparent f/d ratios for the Sand Pwave amplitudes of nonleptonic hyperon decays is proposed. The argument is formulated in the framework of the standard pole model with (56, 0+) ground-state and (70, 1−) excited baryons as intermediate states for the Pand Swaves respectively. Under the assumption that the dominant part of the deviation of (f...
