Abstract

The forward-backward asymmetry α(s,Δ²) has been extrapolated to both the pion pole and to the ππ threshold in a manner that is consistent with the general form of the off-mass-shell dependence of current algebra. We have determined the P-wave and the isoscalar S-wave ππ phase shifts near threshold.

An analysis of the Λ (1520) observed in a K<sup>-</sup> neutron production experiment
1975, Nuclear Physics, Section B
The mass, width and branching fractions of the Λ(1520) into $K N, σπ, Λππ and σππ$ have been determined using a Λ(1520) sample produced in the reaction K⁻d→Λ(1520)π⁻p_s at K⁻ -neutron centre-of-mass energies between 1.9 and 2.2 GeV. A Dalitz plot analysis of the Λ⁰π⁺π⁻ decay mode shows that there is a substantial Σ(1385)π component. The SU(3) octet-singlet mixing angle for the $32^{−}$ baryons calculated from the partial widths for the s-wave σ(1385)π decay of the Λ(1520) and Λ(1690) is found to be consistent with that obtained from the d-wave decays of the singlet and octet members, within experimental limits.

Test of crossing symmetry on low-energy ππ S- and P-wave models using crossing relations on the physical region
1973, Nuclear Physics, Section B
We use the crossing relations on the physical region as a test of the crossing properties of various ππ S- and P-wave models in a scheme containing as a first input the ϱ-meson's existence and elastic unitarity. These relations appear to be selective but are unable to remove some ambiguities like the up-down one.
We also build a parametrization of the partial waves especially suited for these new relations. We find a wide class of S-waves which fulfill the requirements of elastic unitarity, crossing symmetry and ϱ-meson existence in the P-wave. However, their low energy behaviour remains in agreement with previous predictions.
