The production of K+K- pairs in proton-proton collisions at 2.83 GeV
Q. J. Ye, M. Hartmann, Y. Maeda +30
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…
Momentum dependence of the phi-meson nuclear transparency
M. Hartmann, Yu. T. Kiselev, A. Polyanskiy +29
The production of phi mesons in proton collisions with C, Cu, Ag, and Au targets has been studied via the phi -> K+K- decay at an incident beam energy of 2.83 GeV using the ANKE de…
The production of K+K- pairs in proton-proton collisions below the phi meson threshold
Q. J. Ye, M. Hartmann, D. Chiladze +21
The pp -> ppK+K- reaction was measured below the phi threshold at a beam energy of 2.568 GeV using the COSY-ANKE magnetic spectrometer. By assuming that the four-body phase space i…
Kaon pair production in proton-nucleus collisions at 2.83 GeV kinetic energy
Yu. T. Kiselev, M. Hartmann, A. Polyanskiy +23
The production of non-phi K+K- pairs by protons of 2.83 GeV kinetic energy on C, Cu, Ag, and Au targets has been investigated using the COSY-ANKE magnetic spectrometer. The K- mome…
Measurement of the in-medium phi-meson width in proton-nucleus collisions
A. Polyanskiy, M. Hartmann, Yu. T. Kiselev +25
The production of phi mesons in the collisions of 2.83 GeV protons with C, Cu, Ag, and Au at forward angles has been measured via the phi -> K+K- decay using the COSY-ANKE magnetic…
Measurement of spin observables in the quasi-free np-> {pp}_s pi- reaction at 353 MeV
S. Dymov, V. Shmakova, T. Azaryan +54
The transverse spin correlations A_{x,x} and A_{y,y} have been measured in the pol{d} pol{p} -> p_spec {pp}_s pi- reaction at COSY-ANKE at 353 MeV per nucleon. Here {pp}_s denotes…
Comparison of inclusive K+ production in proton-proton and proton-neutron collisions
Yu. Valdau, V. Koptev, S. Barsov +13
The momentum spectra of K+ produced at small angles in proton-proton and proton-deuteron collisions have been measured at four beam energies, 1.826, 1.920, 2.020, and 2.650 GeV, us…
