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

Ciborowski, J. ; Gwizdz, J. ; Kielczewska, D. ; et al.
J.Phys.G 8 (1982) 13-32, 1982.
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.

PI- P ELASTIC SCATTERING IN THE REGION OF THE X0 (957.6) THRESHOLD

Moissidis, P.G. ; Sarma, H.N.K. ; Carr, J. ; et al.
Nuovo Cim.A 75 (1983) 123-162, 1983.
Inspire Record 196214 DOI 10.17182/hepdata.8694

We present results from a high-momentum-resolution measurement of the π-p elastic differential and total cross-sections-at values of cos θ* between — 0.60 and 0.85 in the centre-of-mass system and at incident-beam momenta between 1.34GeV/c and 1.49 GeV/c—close to the X0 production threshold. There is no significant enhancement near the X0 production threshold. However, a small effect of ~ 3 standard deviations is present, having mass 1898.8 MeV and width ~5MeV, and appearing at an incident-pion momentum of 1435 MeV/c. In addition, a narrow ~ 5-standard-deviation effect atEc.m.= 1876 MeV appeared at an incident-pion momentum of 1389 MeV/c.

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.

The pi+ p interaction at 1.2 gev/c

Berthon, A. ; Mas, J. ; Narjoux, J.L. ; et al.
Nucl.Phys.B 81 (1974) 431-444, 1974.
Inspire Record 93412 DOI 10.17182/hepdata.7945

Experimental results are presented for the available channels in the 1.2 GeV/ c π + p interaction. An isobaric model with incoherent addition of the amplitudes is used to determine the π, Δ and N ∗ abundance rates in the π + π o p final state. The multipole parameters in the density matrix of the Δ ++ are determined as functions of its production angle.
