Two-body hyperon final states in antiproton interactions at 2.2 gev/c

Kwak, N. ; Manweiler, J.E. ; Nicholas, M.L. ;
Nuovo Cim.A 23 (1974) 610-617, 1974.
Inspire Record 97002 DOI 10.17182/hepdata.37751

The reactions\(\bar pp \to \bar \Lambda \Lambda \),\(\bar \Lambda \Sigma ^0+ C.C.\),\(\bar \Sigma ^ +\Sigma ^ +\) and\(\bar \Sigma ^ -\Sigma ^ -\) are studied at 2.2 GeV/c. The cross-section, differential cross-section, polarization and spin correlations (between the\(\bar \Lambda \) and Λ hyperons) are discussed.

A comparison of the production of k*(890) in k+ p and k- p interactions

Carney, J.N. ; Colley, D.C. ; Jobes, M. ; et al.
Phys.Lett.B 42 (1972) 124-128, 1972.
Inspire Record 85042 DOI 10.17182/hepdata.28222

Results are presented on an analysis of the reaction K + p → K ∗+ (890) p at 16 GeV/ c and compared with data at lower incident momenta and with corresponding results for the reaction K − p → K ∗− (890) p. It is found for both reactions that the energy dependence of the cross section exhibits a simple ( p − n lab behaviour.

The inclusive single-particle spectra of pi-, K0(s) and Lambda in proton proton collisions at 19-GeV/c

The Scandinavian Bubble Chamber collaboration Boeggild, H. ; Dahl-Jensen, E. ; Hansen, K.H. ; et al.
Nucl.Phys.B 57 (1973) 77-99, 1973.
Inspire Record 84068 DOI 10.17182/hepdata.32535

Data on the inclusive production spectra of K S 0 and Λ from proton-proton collisions at 19 GeV are presented and discussed in connection with the earlier studied inclusive π − production spectrum. The three single-particle spectra are compared with a crude two-center thermal model for the average radiation from the pp collisions.

Production of $\gamma, \Lambda^0, K^0_s$ and $\bar \Lambda^0$ in pp Collisions at 102 GeV/c.

Chapman, J.W. ; Cooper, John W. ; Green, N. ; et al.
Phys.Lett.B 47 (1973) 465-468, 1973.
Inspire Record 81963 DOI 10.17182/hepdata.28029

We have measured cross section for γ , K S °, Λ and Λ production at 102 GeV/ c and find: σ ( γ ) = 170 ± 16 mb ., σ ( K S °) = 4.6 ± 0.5 mb ., σ ( Λ ) = 3.2 ± 0.4 mb ., and σ( Λ ) = 0.23 ± 0.10 mb. Both 〈 n π °〉 and 〈 n Ks °〉 appear to rise linearly with n - while the ratio 〈 n Ks °〉/〈 n π °〉 is approximately independent of n - . The integrated invariant cross section as a function of x as well as d σ /d y and d σ /d p T 2 are presented and compared with other data.

Elastic scattering and single-pion production in k- p interactions at 5.5 gev/c

Engelmann, R. ; Musgrave, B. ; Schweingruber, F. ; et al.
Phys.Rev.D 5 (1972) 2162-2187, 1972.
Inspire Record 74221 DOI 10.17182/hepdata.22545

We present results of an analysis of two-prong events for elastic scattering and single-pion production in K−p interactions at 5.5 GeVc. The resonance parameters for the charged and neutral K*(890) and K*(1420) are determined and the observed production and decay properties of the charged and neutral K*(890) are compared with the theoretical predictions of an absorptive one-particle-exchange model and a Regge model. The K*(1420) differential cross section and density-matrix elements are presented and the question of whether more than one resonance exists in this mass range is considered. A search for resonance effects at Kπ mass beyond 1500 MeV is made. In particular, the recently reported state at 1800 MeV is discussed. A B5-model analysis of the reaction K−p→K¯0π−p is also presented.
