Measurement of gamma p ---> K+ Lambda and gamma p ---> K+ Sigma0 at photon energies up to 1.47-GeV

Bockhorst, M. ; Burbach, G. ; Burgwinkel, R. ; et al.
Z.Phys.C 63 (1994) 37-47, 1994.
Inspire Record 380478 DOI 10.17182/hepdata.14114

The reactions γp→K+ Λ and γp→K+ Σ0 have been measured with the multiparticle detector system SAPHIR at ELSA in Bonn. Besides the differential cross sections the Λ polarization and, for the first time, the Σ0 polarization have been determined in a photon induced reaction. All data are presented as functions of the photon energy (from threshold up to 1.47 GeV) and of the kaon production angle (0°–180°). The polarization of both Λ and Σ0 is substantial at all energies and varies strongly with the production angle.

A STUDY OF THE REACTIONS ANTI-K0 P ---> LAMBDA PI+ (BACKWARD) AND ANTI-K0 P ---> SIGMA0 PI+ (BACKWARD) FOR KAON MOMENTA BETWEEN 1 AND 8-GEV/C

Inspire Record 159454 DOI 10.17182/hepdata.34465

We present results for the reactions K 0 p →Λπ + and K 0 p →∑ 0 π + , for |u'| <0. 05 ( GeV /c) 2 and kaon momenta between 1 and 8 GeV/ c . The experiment was performed ina neutral beam at the PS with a two arm spark chamber spectrometer. The cross sections show strong dependence on beam energy and momentum transfer u ′. Λ polarization is compatible with zero. We compare energy dependence of the backward cross sections with the baryon exchange model from π N scattering.

MEASUREMENT OF POLARIZATION IN K- p ELASTIC SCATTERING BETWEEN 0.955-GeV/c AND 1.272-GeV/c

Bryant, H.C. ; Carter, A.A. ; Coupland, M. ; et al.
Nucl.Phys.B 168 (1980) 207-221, 1980.
Inspire Record 143628 DOI 10.17182/hepdata.34502

The polarization parameter has been measured for K − p elastic scattering at nine incident beam momenta between 0.955 and 1.272 GeV/ c covering the c.m. angular range −0.9 < cos θ ∗ < + 0.9 . Experimental results and coefficients of Legendre polynomial fits to the data are presented and compared with other measurements and a partial-wave analysis.

We have measured the production cross section for K s 0 in e + e − annihilation from 3.6 to 5.0 GeV center of mass energy. A substantial increase of the K s 0 yield is observed around 4 GeV in qualitative agreement with the charm hypothesis.
