Kaon pair production in proton-proton collisions at COSY-ANKE
The near-threshold production of kaon-pairs has been investigated in protonproton collisions at Cooler Synchrotron (COSY)at Forschungszentrum Jülich. In the pp → ppKK reaction, the invariant mass distributions of Kp, Kpp, and KK indicate the presence of both Kp and KK final state interactions. Total cross sections for pp → ppφ reaction have been determined at excess energies ε of 18.5, 34.5, an...
متن کاملHeavy Flavor Production at the electron-proton collider HERA
An overview over the recent heavy flavor results of the H1 and ZEUS collaborations is presented. Various techniques to tag the heavy quark, which allow to explore different phase space regions, are employed. Predictions of pertubative QCD are compared to the charm and beauty production data. Charm and beauty fractions of the proton structure function F2 are extracted.
متن کاملNear Threshold KK Meson-Pair Production in Proton-Proton Collisions
The near threshold total cross section and angular distributions of KK pair production via the reaction pp −→ ppKK have been studied at an excess energy of Q = 17 MeV using the COSY-11 facility at the cooler synchrotron COSY. The obtained cross section as well as an upper limit at an excess energy of Q = 3 MeV represent the first measurements on the KK production in the region of small excess e...
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 کاملDilepton production in proton-proton collisions at BEVALAC energies
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 ...
