Title: Production of K⁺K⁻ pairs in proton-proton collisions at 2.83 GeV

Abstract

Differential and total cross sections for the pp→ppK⁺K⁻ reaction have been measured at a proton beam energy of 2.83 GeV using the COSY-ANKE magnetic spectrometer. Detailed model descriptions fitted to a variety of one-dimensional distributions permit the separation of the pp→ppφ cross section from that of non-φ production. The differential spectra show that higher partial waves represent the majority of the pp→ppφ total cross section at an excess energy of 76 MeV, whose energy dependence would then seem to require some s-wave φp enhancement near threshold. The non-φ data can be described in terms of the combined effects of two-body final state interactions using the same effective scattering parameters determined from lower energy data.

Production of K⁺K⁻ pairs in proton-proton collisions below the Φ meson threshold

Journal Article Ye, Q. J. ; Hartmann, M. ; Chiladze, D. ; ... - Physical Review. C. Nuclear Physics

The pp→ppK⁺K⁻ reaction was measured below the Φ threshold at a beam energy of 2.568 GeV using the COSY-ANKE magnetic spectrometer. By assuming that the four-body phase space is distorted only by the product of two-body final-state interactions, fits to a variety of one-dimensional distributions permit the evaluation of differential and total cross sections. The shapes of the distributions in the K_p and K_pp invariant masses are reproduced only if the K⁻_p interaction is even stronger than that found at higher energy. The cusp effect in the K⁺K⁻ distribution at the K⁰K¯¯¯⁰ threshold is much more clear and some evidencemore »« less

Kaon pair production in proton-proton collisions

Journal Article Maeda, Y ; Hartmann, M ; Buescher, M ; ... - Physical Review. C, Nuclear Physics

The differential and total cross sections for kaon pair production in the pp{yields}ppK{sup +}K{sup -} reaction have been measured at three beam energies of 2.65, 2.70, and 2.83 GeV using the ANKE magnetic spectrometer at the COSY-Juelich accelerator. These near-threshold data are separated into pairs arising from the decay of the {phi}-meson and the remainder. For the non-{phi} selection, the ratio of the differential cross sections in terms of the K{sup -}p and K{sup +}p invariant masses is strongly peaked toward low masses. This effect can be described quantitatively by using a simple ansatz for the K{sup -}p final statemore »« less

Measurement of the pn{yields}dK{sup +}K{sup -} total cross section close to threshold

Journal Article Maeda, Y ; Hartmann, M ; Buescher, M ; ... - Physical Review. C, Nuclear Physics

Measurements of the pd{yields}p{sub sp}dK{sup +}K{sup -} reaction, where p{sub sp} is a spectator proton, have been undertaken at the Cooler Synchrotron COSY-Juelich by detecting a fast deuteron in coincidence with a K{sup +}K{sup -} pair in the ANKE facility. Although the proton beam energy was fixed, the moving target neutron allowed values of the nonresonant quasifree pn{yields}dK{sup +}K{sup -} total cross section to be deduced up to an excess energy {epsilon}{approx_equal}100 MeV. Evidence is found for the effects of K{sup -}d and KK final state interactions. The comparison of these data with those of pp{yields}ppK{sup +}K{sup -} and pp{yields}dK{supmore »« less

Investigation of K{sup +}-meson production in pp and pA collisions with ANKE

Journal Article Buescher, Markus - AIP Conference Proceedings

The production of K{sup +}-mesons in proton-nucleus collisions has been measured with the ANKE spectrometer at COSY-Juelich. The kaons, produced on internal C, Cu and Au targets and emitted under forward angles {theta}{sub K}{approx}0 deg., were separated from the circulating COSY beam and momentum analyzed with the help of a chicane-like magnetic system. Double differential spectra were obtained for beam energies T{sub p}=1.0...2.3 GeV, thus above and far below the free nucleon-nucleon threshold at T{sub NN}=1.58 GeV. The data taken at T{sub p}=1.0 GeV reflect a high degree of collectivity of the target nucleus. For T{sub p}{>=}1.2 GeV the invariantmore »« less

Measurement of the in-medium Φ-meson width in proton–nucleus collisions

Journal Article Polyanskiy, A. ; Hartmann, M. ; Kiselev, Yu. T. ; ... - Physics Letters B

We measured the production of Φ mesons in the collisions of 2.83 GeV protons with C, Cu, Ag, and Au at forward angles via the Φ → K⁺K^- decay using the COSY-ANKE magnetic spectrometer. The Φ meson production cross section follows a target mass dependence of A^0.56±0.02 in the momentum region of 0.6-1.6 GeV/c. Moreover, the comparison of the data with model calculations suggests that the in-medium Φ width is about an order of magnitude larger than its free value.
