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 کاملSelf-similarity of strangeness production in pp collisions at RHIC
New experimental data on transverse momentum spectra of strange particles (K S ,K −,K∗, φ, ...) produced in pp collisions at √ s = 200 GeV obtained by the STAR and PHENIX collaborations at RHIC are analysed in the framework of z-scaling approach. Scaling properties of the data z-presentation are illustrated. Self-similarity of strange particle production is discussed. A microscopic scenario of ...
متن کاملPhi Meson Production in Heavy-Ion Collisions at SIS Energies
Phi meson production in heavy-ion collisions at SIS/GSI energies (∼ 2 GeV/nucleon) is studied in the relativistic transport model. We include contributions from baryon-baryon, pion-baryon, and kaon-antikaon collisions. The cross sections for the first two processes are obtained in an one-bosonexchange model, while that for the last process is taken to be of Breit-Wigner form through the phi mes...
متن کاملInclusive Prompt Photon Production in Polarized pp Collisions at HERA
We present a NLO study of inclusive polarized prompt photon production in a conceivable fixed target pp mode of HERA with longitudinally polarized protons at √ s = 39 GeV. We analyze the sensitivity of the corresponding double spin asymmetry to the proton’s polarized gluon distribution ∆g and estimate the expected statistical precision in its determination. The main theoretical uncertainties in...
متن کاملCHARMONIUM AND BOTTOMONIUM PRODUCTION IN pp COLLISIONS AT CDF
We present measurements of charmonium and bottomonium production using a data sample collected by CDF during the 1992-93 pp collider run at the Fermilab Tevatron. Previous CDF measurements of J/ψ and ψ(2S) production during the 1988-89 collider run showed production cross sections considerably larger than contemporary theory predicted. This drew theoretical interest, but at the time the questio...
