Strange Particle Production Mechanisms in Proton-Proton Collisions at RHIC
Abstract. We present data on strange particle production in elementary proton-proton collisions at RHIC energies. Comparison to leading order and next-to-leading order (NLO) calculations shows that the fragmentation process is flavor dependent and that higher order corrections are needed to describe all spectra, in particular at these collision energies, which are modest compared to the Tevatro...
متن کاملφ-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 کاملStrangeness production in proton - proton and proton - nucleus collisions ∗
In these lectures we discuss the investigation of the strange meson production in protonproton (pp) and in proton-nucleus (pA) reactions within an effective Lagrangian model. The kaon production proceeds mainly via the excitations of N(1650), N(1710), and N(1720) resonant intermediate nucleonic states, in the collision of two initial state nucleons. Therefore, the strangeness production is expe...
متن کاملProton-proton collisions at production thresholds
Recent results obtained by the COSY – 11 collaboration concerning the production of η and η mesons in the pp → ppMeson reaction are presented. A comparison of the production amplitude for the π, η and η mesons at the same phase space volume allows to conclude that the proton η interaction is in the order of, or smaller than, the proton-π one. A total cross section determined in a preliminary an...
متن کاملStrangeness production as a function of charged particle multiplicity in proton-proton collisions
Recent measurements performed in high-multiplicity proton-proton (pp) and proton-lead (p-Pb) collisions have shown features that are reminiscent of those observed in lead-lead (Pb-Pb) collisions. These observations warrant a comprehensive measurement of the production of identified particles. We report on the production of K0 S , Λ, Λ, Ξ ± and Ω± at mid-rapidity measured as a function of multip...
