Inclusive $K^*$+ (892) and $K^*$ (892) Production in $K^+ p$ Interactions at 32-{GeV}/c

The French-Soviet & CERN-Soviet collaborations Azhinenko, I.V. ; Bryzgalov, V.V. ; Gerdyukov, L.N. ; et al.
Z.Phys.C 5 (1980) 177, 1980.
Inspire Record 153557 DOI 10.17182/hepdata.71085

Total and semi-inclusive cross sections, longitudinal and transverse momentum distributions and spin density matrix elements of theK*+(892) andK*0(892) produced in the inclusive reactionsK+p→K*+(892)+X andK+p→K*0(892)+X at 32 GeV/c are studied in detail. The inclusive spectra of theK*(892) and their decay products are compared with pion and neutral kaon production. TheK*+(892) andK*+(892) are dominantly produced by kaon fragmentation processes. The dependence of average transverse momentum <pT> vs.x for resonances has been investigated for the first time.

Inclusive Production of Nonstrange Resonances in $K^- p$ Interactions at 32-{GeV}/$c$

The French-Soviet & CERN-Soviet collaborations Arestov, Yu. ; Borovikov, A. ; Kozlovsky, E. ; et al.
Z.Phys.C 8 (1981) 283, 1981.
Inspire Record 155144 DOI 10.17182/hepdata.41428

New data on the inclusive production of the non-strange resonances ϱ0(770), ω(783), ϕ(1020) andf(1270) inK− p interactions at 32 GeV/c are presented. The inclusive production cross sections are equal to (4.32±0.72) mb, (3.7±1.4) mb, (0.65±0.10) mb and (0.91±0.35) mb respectively. Estimates of the topological cross sections are also obtained. The invariant and non-invariantx-distributions for the vector mesons ϱ0 and ϕ indicate the prevalence of forward resonance production in the c.m. system. For the tensorf-meson the rapidity andx-distributions are presented. Thet′-distributions for ϱ0, ϕ, andf have exponential slopes of 0.6±0.1 GeV−2, 1.2±0.2 GeV−2, and 0.8±0.5 GeV−2 respectively. The exponential slope ofpT2-distribution of thef-meson is equal to (2.3±0.5) GeV−2.

Inclusive Production Cross-Sections of Resonances in 32-GeV/c K+ p Interactions

The French-Soviet & CERN-Soviet collaborations Granet, P. ; Mosca, L. ; Saudraix, J. ; et al.
Nucl.Phys.B 140 (1978) 389, 1978.
Inspire Record 121746 DOI 10.17182/hepdata.34983

The inclusive production of resonances is systematically studied in K + p interactions at 32 GeV/ c . Total production cross sections are given for three baryon resonances, five vector and three 2 + tensor mesons. We also compare the central and fragmentation components of the total production cross sections with quark model predictions.

Exclusive Reactions in $\bar{p} p$ Interactions at 32-{GeV}/$c$

The French-Soviet & CERN-Soviet collaborations Jabiol, M.A. ; Denegri, D. ; Louedec, C. ; et al.
Nucl.Phys.B 183 (1981) 330-348, 1981.
Inspire Record 155103 DOI 10.17182/hepdata.34313

The cross sections of several exclusive reactions in p p interactions are given. In the channels p p → p p π + π − and p p → p p 2π + 2π − which dominate the interactions, the single and double diffractive dissociations are analysed and compared to the results obtained with K ± p interactions at the same energy, pp and p p interactions at other energies. The test of factorization at the p → p π + π − vertex is well verified. The process p p → Δ ++ Δ ++ is studied and the cross sections of Δ ++ , Δ ++ , ϱ 0 and f 0 production are also given.

Channel Cross-sections and Two-body Reactions in $K^- p$ Interactions at 32-{GeV}/$c$

The French-Soviet & CERN-Soviet collaborations Givernaud, A. ; Denegri, D. ; Lewin, C. ; et al.
Nucl.Phys.B 160 (1979) 445-466, 1979.
Inspire Record 141995 DOI 10.17182/hepdata.34613

We present a systematic investigation of channel cross sections in K − p interactions at 32 GeV/ c . The energy dependence of these cross sections is discussed. We also investigate a few non-diffractive two-body reactions. The total cross sections of the two reactions K − p → K ∗− (890) p and K − p → K ∗− (1420) p have a markedly different energy behaviour. There is clear evidence for the reaction K − p → K ∗0 (890) N 0 (1688) ; its differnttial cross section exhibits a sharp forward slope of 24 ± 3 GeV −2 .

Neutral Kaon Production in K+ p Interactions at 32-GeV/c

The French-Soviet & CERN-Soviet collaborations Gerdyukov, L.N. ; Gorbunov, P.A. ; Klimenko, S.V. ; et al.
Nucl.Phys.B 133 (1978) 93, 1978.
Inspire Record 122185 DOI 10.17182/hepdata.35163

The production of neutral kaons in the reaction K + p → K n + X is studied at the incident momentum of 32 GeV/ c . Inclusive cross sections and single-particle distributions are presented and compared with the data at lower energies. The total inclusive cross section amounts to 7.9 ± 0.3 mb at 32 GeV/ c and is significantly higher than at lower energies due to the rapid rise of multikaon production. The fraction of K n 's coming from the decay of the K ∗ resonances stays roughly constant with energy between 8.2 and 32 GeV/ c . In the central and beam fragmentation regions the single-particle distributions reveal no energy dependence between the 16 and 32 GeV/ c data in contrast with the behaviour at lower energies, while in the proton fragmentation region the data are compatible with the trend observed at lower energies and with theoretical expectations.
