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

Ciborowski, J. ; Gwizdz, J. ; Kielczewska, D. ; et al.

Inspire Record 179889 DOI 10.17182/hepdata.38531

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.

Reactions $K^- p \to \Sigma^- \pi^+$ and $K^- p \to \Sigma^+ \pi^-$ in the Momentum Range From 220-{MeV}/c to 470-{MeV}/c

We present the analysis of 64 000 K−p→Σ−π+ and 89 000 K−p→Σ+π− events obtained with the Berkeley 25-in. hydrogen bubble chamber. Total cross sections and Legendre-polynomial expansion coefficients describing the differential cross sections and polarizations are presented in 10-MeV/c momentum intervals extending from 220 to 470 MeV/c. This paper completes the series devoted to all K−p final states in this momentum range.

New High Statistics Data on $K^- p \to$ Two-body Final States Over the Center-of-mass Energy Range 1720-{MeV} to 1796-{MeV}

Cameron, W. ; Franek, B. ; Gopal, G.P. ; et al.
Nucl.Phys.B 193 (1981) 21-52, 1981.
Inspire Record 156542 DOI 10.17182/hepdata.2930

Data are presented from a high statistics bubble chamber experiment to K − p interactions over the c.m. energy range 1720 to 1796 MeV. Channel cross sections, differential cross sections and, where appropriate, polarisation distributions have been obtained for the final states K − p , K 0 n , π 0 Λ and π ± Σ ∓ . These data are compared with those from previously published experiments and with the predictions from the RL-IC 77 partial-wave amplitudes for each of these channels.

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

Nuovo Cim.A 37 (1977) 175, 1977.
Inspire Record 100939 DOI 10.17182/hepdata.37615

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.
