Results are presented on total and semiinclusive cross sections, longitudinal and transverse momentum distributions of the tensor mesonsK*+(1430),K*0(1430), andf(1270) observed inK+p interactions at 32 GeV/c. The data are compared withK*+(892).K*0(896) and ϱ0 vector meson production in the same experiment. The shapes of inclusive invariantx-spectra for the strange vector and tensor mesons are found to be rather similar, after removal of diffractive and quasi-two-body channels, in agreement with quark-recombination ideas.

Comparison of Strange Anti-baryon and Strange Meson Production in $K^+ p$ Interactions at 32-{GeV}/$c$

Chliapnikov, P.V. ; Gerdyukov, L.N. ; Khromova, G.N. ; et al.

Z.Phys.C 12 (1982) 99, 1982.

Inspire Record 167341 DOI 10.17182/hepdata.10880

New experimental results are presented on inclusive production properties of$\bar \Sigma ^{ *+ } $(1385) and$\bar \Sigma ^{ *+ } $(1385) inK+p interactions at 32 GeV/c. The analysis is based on significantly larger statistics than previously available. A comparison is also made of invariantx-distributions ofK0/$\bar K^0 $,$\bar \Lambda $ and$\bar \Xi ^ +$ and of$\bar \Sigma ^{ *\pm } $(1385) andK*+(892). These spectra exhibit regularities expected from the quark-recombination picture when it is assumed that the strange mesons and antibaryons are produced off the strange$\bar s$-valence-quark in the incidentK+ meson. Transverse momentum distributions are also presented forK*+(892) and$\bar \Sigma ^{ *\pm } $(1385) and found to be very similar. The results on strange antibaryon average multiplicities disagree strongly with a recent version of the additive quark model.

Inclusive Production of $\rho^0$ and $\phi$ in $K^+ p$ Interactions at 32-{GeV}/c

Inclusive ϱ 0 and φ production is investigated in K + p interactions at 32 GeV/ c . Total and semi-inclusive ϱ 0 and φ cross sections, longitudinal and transverse momentum distributions, including 〈 P T versus x dependence are presented. No evidence for a sea-gull effect is observed. Comparison with quark models strongly suggests the possibility that a large fraction of the ϱ 0 and vector mesons are produced as fragmentation products of the incident particles. Study of uncorrelated π + π − pairs in the ϱ 0 mass range provides possible indirect evidence for the existence of diquarks in the proton.

The reaction of tp → pdn in 4π geometry was investigated by exposition of an 80 cm liquid hydrogen bubble chamber to a t-nucleus beam of 2.5 GeV/ c momentum. The main characteristics of the reaction are described reasonably well by the pole approximation in the absolute normalization and without free parameters.
