KAON SCATTERING AND CHARGED SIGMA HYPERON PRODUCTION IN K- P INTERACTIONS BELOW 300-MEV/C

In an experiment on K--proton interactions in a hydrogen bubble chamber, the cross sections and angular distributions have been studied for elastic and charge-exchange scattering, and charged sigma hyperon production in the momentum range 90-300 MeV/c. Good agreement is found with previous cross sections except for the charge-exchange channel where the new values are 60% larger. The production distributions of the charged sigma hyperons and the polarisation of the Sigma + hyperon clearly indicate that P waves are present down to about 150 MeV/c, much lower than previously reported.

K- n ---> sigma- eta near threshold

The reaction K−n→Σ−η has been studied near threshold. The production angular distribution and the cross-section as a function of energy were measured. The combined angular distributions of this experiment and two previous ones suggest that aJ=1/2 amplitude dominates in Σ−η production. Our cross-section can be fitted with a Σ−1η resonance of mass 1785±12 and width 89±33, or it can be fitted in a zero-effective-range scattering approximation with a scattering length of (0.92±0.12)±i(0.04±0.28) fm.

New Data on the Reaction K- p --> Sigma+- pi+- from 1.934-GeV/c to 2.516-GeV/c and Partial Wave Analysis for These Reactions, Between 2070-MeV and 2436-MeV CMS Energy

We present the results of a formation experiment for the reactions K±p→Σ±π± in the c.m.s. energy between 2200 and 2436 MeV with a total statistics of 10 ev/μb. A partial-wave analysis including these new data gives evidence for the existence of three resonances in theD15,G19 andH09 states and confirms the existence of anF05 state.
