K0(L) p Interactions at 550-MeV/c

Cho, Y. ; Derrick, M. ; Miller, R.J. ; et al.
Phys.Lett.B 60 (1976) 293-296, 1976.
Inspire Record 2899 DOI 10.17182/hepdata.27718

Differential and channel cross sections and hyperon polarizations are presented for the reactions K L o p → K S o p, π + Λ o , and π + Σ o at an average beam momentum of 550 MeV/ c . These data provide constraints on KN and K N amplitudes obtained from charged kaon reactions and reject one of the S = +1, I = 0 and one of the S = -1, I = 1 phase shift solutions.

Study of the anti-K0 p --> Lambda pi+, Sigma0 pi+ Reactions in the Energy Range of 1.5-GeV to 2.3-GeV

The total and differential cross sections of the K¯0p→Λπ+ and K¯0p→∑0π+ reactions have been measured in the centre-of-mass energy range of l.5 to 2.3 GeV. Using our K¯0p→∑0π+ data as well as available cross-section data of isospin related channels, we have calculated the total I=0K¯N→∑π cross section as function of energy. The results are compared with predictions obtained from K¯N phase-shift analyses.

The Reaction pi- p --> eta n Up to rho* (eta) = 450-MeV/c: Experimental Results and Partial Wave Analysis

Feltesse, J. ; Ayed, R. ; Bareyre, P. ; et al.
Nucl.Phys.B 93 (1975) 242-260, 1975.
Inspire Record 99411 DOI 10.17182/hepdata.32003

An accurate measurement of d σ d Ω (π − p → η n ) at 1531 MeV total energy (expanded) up to l = 4 Legendre polynomials) requires reconsideration of previous angular distribution fits which were expanded only up to l = 2 and of subsequent partial-wave analysis. An energy-dependent partial-wave analysis has been performed here for p η ∗ up to 450 MeV/ c . In addition to the well-known S 11 (1520 MeV) resonance, either the P 11 (1532 MeV) or the P 13 (1530 MeV) resonance is found to be strongly coupled to the η-n channel. In both cases, the P 11 (1729 MeV) resonance is needed as is the weakly coupled D 13 (1525 MeV) resonance. The decay states in the ηn channelare compared to the SU(3) and SU(6) W predictions.

Charge exchange and production of eta mesons and multiple neutral pions in pi- p reactions between 654 and 1247 mev/c

Bulos, F. ; Lanou, R.E. ; Piper, A.E. ; et al.
Phys.Rev. 187 (1969) 1827-1844, 1969.
Inspire Record 62084 DOI 10.17182/hepdata.5293

An experiment designed to study the π−p total neutral cross section and its breakdown into several channels has been performed at eleven incident pion momenta ranging from 654 to 1247 MeV/c. Angular distributions for the charge exchange π0 and for η0 production are given in terms of Legendre-polynomial expansion coefficients. Forward and backward differential cross sections are presented for the charge-exchange channel and comparisons with recent dispersion-relation predictions for the forward cross section are made.
