Kaon pair production in pp, pd, dd and pA collisions at COSY — •Michael Hartmann1, Andrey Polyanskiy1, and Qiujian Ye1,2 — 1Institut für Kernphysik, Forschungszentrum Jülich, 52425 Jülich, Germany — 2Physics Department, Duke University, Durham, NC 27708, USA
The near-threshold production of φ-mesons decaying into K+K−, as well as non-resonant (KK) pairs, has been investigated in proton-proton, proton-deuteron and deuteron-deuteron collisions at the Cooler Synchrotron COSY. These data are sensitive to some of the interactions in the Kp, KK, and φ p channels. Studies of φ production in proton-nucleus collisions have also been recently undertaken. A review of the results obtained over the last few years will be given, together with a forward look on the ongoing investigations.
