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…
