Al-Alawi, Jasem (1996) Role of parity violating Hamiltonian in-non-relativistic quark model for non-leptonic hyperon weak transitions. Masters thesis, King Fahd University of Petroleum and Minerals.
A non-relativistic quark model has been used in the calculation of the K*-pole contributions to s-wave amplitudes for non-leptonic decays of hyperons, which involve K*⁰- π⁰ and K*⁻- π⁻ weak transitions. Such corrections were thought to be one way of removing the long standing discrepancy between s- and p- wave amplitudes obtained in the current-algebra approach to non-leptonic decays of hyperons. Although the calculation of the K* contribution on the quark model is found to be negligible, it gives the right order of magnitude of small observed deviations form the ΔI=1/2 rule. A comparison of the observed deviation from ΔI=1/2 rule for s-wave hyperon decay amplitudes with estimated ones is discussed.
