Abstract(summary):

The production of mesons in the collisions of 2.83 GeV protons with C, Cu, Ag, and Au at forward angles has been measured via the →K+K decay using the COSY-ANKE magnetic spectrometer. The meson production cross section follows a target mass dependence of A0.56±0.03 in the momentum region of 0.6–1.6 GeV/c. The comparison of the data with model calculations suggests that the in-medium width is about an order of magnitude larger than its free value.
