φ-meson production in proton-proton collisions
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, ...
متن کاملAspects of φ-meson production in proton-proton collisions
We analyze near-threshold cross section data for the reaction pp→ppφ published by the DISTO collaboration and recent, still preliminary results presented by the ANKE Collaboration. We formulate a procedure to evaluate the OZI ratio at low energies by taking into account corrections from the kinematics and the final-state interaction. Combining the new data with the few measurements available at...
متن کاملSubthreshold φ meson production in heavy-ion collisions
Within a transport code of BUU type the production of φ mesons in the reactions Ni + Ni at 1.93 A·GeV and Ru + Ru at 1.69 A·GeV is studied. New elementary reaction channels ρN(∆) → φN and πN(1520) → φN are included. In spite of a substantial increase of the φ multiplicities by these channels the results stay below the tentative numbers extracted from experimental data.
متن کاملφ- meson Production at RHIC energies using the PHENIX Detector
Light vector mesons are among the most informative probes to understand the strongly coupled Quark Gluon Plasma created at RHIC. The suppression of light mesons at high transverse momentum, compared to expectations from scaled p + p results, reflects the properties of the strongly interacting matter formed. The φ-meson is one of the probes whose systematic measurement in p + p, d + Au and Au + ...
متن کاملMeasuring the φ meson width in the medium from p induced φ production in nuclei
1 Measuring the φ meson width in the medium from p induced φ production in nuclei We study the A dependence of the φ meson production cross section in proton nucleus reactios at energies just above threshold, which are accessible in an experimental facility like COSY. This A dependence has two sources: the distortion of the incident proton and the absorption of the φ in its way out of the nucle...
