“…for the decay 3/2 + → 1/2 + 0 − one has H λ30 = H −λ30 . This also follows from a simple quark model calculation [54,66]. The fact that the vector current induced transition 3/2 + → 1/2 + is conserved in the simple quark model can be traced to the approximation that there is no spin interaction between the two light spectator quarks [67].…”

Quark and particle helicities in hadronic charmed particle decays

“…[11 ]). Since the latter approach can be seen to be equivalent to an analysis based on quark model diagrams [12][13][14] the quark model approach can be used as an alternative description of the hyperon decays. Also, experiments have shown that the hyperon decay amplitudes are very near to being relatively real.…”

Topological tensor invariants and the current algebra approach: Analysis of 196 nonleptonic two-body decays of single and double charm baryons -- a review

“…In the covariantized constituent quark model (CCQM) calculations [30,37] the quark pair creation from the vacuum is effectively described by the 3 P 0 model where the strength of the 3 P 0 interaction is fixed by a fit to the data. Both of the above papers are based on an approach developed much earlier by F. Hussain and P. Rotelli [38] and by J. G. Körner and T. Gudehus [39] for studying nonleptonic hyperon decays. In the covariant confined quark model calculations of Refs.…”
