Study of the Reaction pi+ p --> K+ Sigma+ Between 1.721-GeV-1.954-GeV Center-Of-Mass Energy

Cross-section, angular distribution and polarization measurements are presented at six incident π + energies for the reaction π + p → K + Σ + . Results at already studied energies are compatible with existing data and roughly agree with predictions of partial-waves analyses. However, new results around 1.920 GeV are in disagreement with such predictions, casting some doubt on the determination of decay branching ratios of the T = 3 2 isobars around this mass into K + Σ + .

Polarization in pi+ p ---> k+ sigma+ backward scattering at 3.5 gev/c

Bradamante, F. ; Conetti, S. ; Daum, C. ; et al.
Phys.Lett.B 44 (1973) 202-206, 1973.
Inspire Record 84846 DOI 10.17182/hepdata.28109

In a counter and wire spark chamber experiment with a polarized target, backward kaons were detected, and the Σ + 's identified by a missing-mass technique. An average polarization of −0.08 ± 0.05 was found for −0.2 < u < 0.1 GeV 2 .

New Limits for the Exotic Exchange Reaction pi- p --> K+ Sigma- at 5-GeV and 8-GeV

Dekkers, D. ; Guillaud, J.P. ; Lepeltier, V. ; et al.
Nucl.Phys.B 131 (1977) 72-79, 1977.
Inspire Record 126514 DOI 10.17182/hepdata.35221

Measurement of the exotic exchange reaction π − p → K + Σ − has been performed at 5 and 8 GeV, in the −0.015 to −0.13 and −0.009 to −0.15 (GeV/ c ) 2 range of t repectively. We give the value near t = 0 of the differential cross section at 5 GeV, 21 −21 +76 nb/(GeV/ c ) 2 , and an upper limit (< 37 nb/GeV/ c ) 2 ) at 8 GeV. As a check the measured differential cross section is given at both energies for the reaction π + p → K + Σ + in the same range of t ★★ ★★ Results presented here were included in the thesis of Doctorat d′Etat by M.N. Minard, Orsay, France, 1976. .
