ANGULAR AND ENERGY DEPENDENCE OF THE CROSS-SECTION AND ANALYZING POWER OF THE REACTION P P ----> D PI+ BETWEEN 725-MEV AND 1000-MEV

The differential cross section and analyzing power of the reaction pp → d π + were measured for nine incident proton energies between 725 and 1000 MeV. A magnetic spectrometer was used to detect either deuterons or pions. Cross-section and analyzing-power angular distributions were respectively fitted with Legendre polynomial and associated Legendre function expansions, the coefficients of which were found to vary smoothly with energy in the vicinity of the alleged 3 F 3 dibaryon resonance.

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.

K- p Reactions from 0.96-GeV/c to 1.355-GeV/c Involving Two-Body Final States

The Rutherford-London collaboration Conforto, B. ; Gopal, G.P. ; Kalmus, G.E. ; et al.
Nucl.Phys.B 105 (1976) 189-221, 1976.
Inspire Record 2769 DOI 10.17182/hepdata.8717

Data are presented from a high statistics bubble chamber experiment to study K − p interactions in the c.m. energy range 1775 to 1957 MeV. For the reactions K − p → K − p, K − p → K 0 n , K − p → Λπ 0 and K − p → Σ ± π ∓ channel cross sections, differential cross sections and, where appropriate, polarisation distributions have been obtained. The channel cross sections for K − p → Σ 0 π 0 are presented. In general the results are in agreement with those previously published although a significant discrepancy has been found in the Σ ± π ∓ cross sections at the lower energies. New measurements of the Σ ± lifetimes have also been obtained ( τ Σ − = 1.49 ± 0.03 × 10 −10 sec, τ Σ + = 0.807 ± 0.013 × 10 −10 sec).
