φ-meson production in proton-proton collisions
نویسندگان
چکیده
The production of φ-mesons in proton-proton collisions is investigated within a relativistic meson-exchange model of hadronic interactions. The experimental prerequisites for extracting the NNφ coupling strength from this reaction are discussed. In the absence of a sufficient set of data, which would enable an accurate determination of the NNφ coupling strength, we perform a combined analysis, based on some reasonable assumptions, of the existing data for both ωand φ-meson production. We find that the recent data from the DISTO collaboration on the angular distribution of the φ meson indicate that the NNφ coupling constant is small. The analysis yields values for gNNφ that are compatible with the OZI rule. PACS: 13.60.Le, 14.20.Dh, 25.10+s, 25.40-h

O ct 2 00 3 Exclusive φ production in proton - proton collisions in the resonance model
Exclusive φ production in proton-proton collisions in the resonance model. Abstract The exclusive φ meson production in proton-proton reactions is calculated within the resonance model. The considered model was already successfully applied to the description of π, η, ρ, ω, ππ production in proton-proton collisions. The only new parameter entering into the model is the ω − φ mixing angle θ mix w...

The role of three-body collisions in φ meson production processes near threshold Abstract: The amplitude of subthreshold φ meson production is calculated using dominant tree-level diagrams for three-body collisions. It is shown that the production can overwhelmingly be described by two-step processes. The effect of the genuine three-body contribution (i.e. the contribution which cannot be facto...
متن کاملThe LUCIAE model predictions on the light vector meson production in proton-proton, proton-nucleus and nucleus-nucleus collisions at 158 A GeV
The LUCIAE model predictions are compared with experimental data on light vector meson (ρ, ω, φ) production in pp, p+Pb and Pb+Pb collisions at 158 A GeV. The model reproduces the general trends of the data, but fails in describing the yield of high-pT vector mesons in the central Pb+Pb collisions. Predictions for In+In and p+A (A varying from Be to U) collisions at 158 A GeV are also presented.

The dilepton production in elementary pp → eeX reactions at BEVALAC energies Tlab = 1 ÷ 5 GeV is investigated. The calculations include direct ee decays of the vector mesons ρ, ω, and φ, Dalitz decays of the π, η-, ρ-, ω-, and φ-mesons, and of the baryon resonances ∆(1232), N(1520), . . . . The subthreshold vector meson production cross sections in pp collisions are treated in a way sufficient ...

η meson production in both proton-proton and proton-neutron collisions is investigated within a relativistic meson exchange model of hadronic interactions. It is found that the available cross section data can be described equally well by either the vector or pseudoscalar meson exchange mechanism for exciting the S 11 (1535) resonance. It is shown that the analyzing power data can potentially b...
