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).

Measurement of e+ e- ---> e+ e- and e+ e- ---> mu+ mu- at SPEAR

Augustin, J.E. ; Boyarski, A. ; Breidenbach, Martin ; et al.
Phys.Rev.Lett. 34 (1975) 233, 1975.
Inspire Record 91755 DOI 10.17182/hepdata.21210

The reactions e+e−→e+e− and e+e−→μ+μ− have been measured at center-of-mass energies 3.0, 3.8, and 4.8 GeV and production angles of 50°<θ<130° over all azimuthal angles. Agreement with quantum electrodynamics is excellent. New limits for cutoff parameters in quantum-electrodynamic-breakdown models are given.

New Data on the Reaction K- p ---> Lambda pi0 from 1.934-GeV/c to 2.516-GeV/c and Partial Wave Analysis for This Reaction, Between 2070-MeV and 2436-MeV CMS Energy

de Bellefon, A. ; Berthon, A. ; Brunet, J. ; et al.
Nucl.Phys.B 90 (1975) 1-19, 1975.
Inspire Record 91427 DOI 10.17182/hepdata.32062

We present the results of a formation experiment for the reaction K − p → Λπ 0 in the cms energy between 2200 and 2436 MeV with a total statistics of 10 eV/μb. A partial-wave analysis including these new data gives evidence for the existence of three resonances in the P 3 , D 5 and G 9 (or H 11 ) states in this mass region.

Observation of Vector Meson Production in Inclusive p p Reactions

The Bonn-Hamburg-Munich collaboration Blobel, V. ; Fesefeldt, H. ; Franz, H. ; et al.
Phys.Lett.B 48 (1974) 73-76, 1974.
Inspire Record 80794 DOI 10.17182/hepdata.27994

We have measured cross sections, rapidity and transverse momentum distributions, and vector meson polarization for the reactions pp→ ϱ o +anything, pp→ ω +charged particles, and pp → K ∗± + anything at incident laboratory momenta of 12 and 24 GeV/ c . We discuss various consequences of our results as well as possible connections with lepton pair production.
