Medium effects on phi-meson production in near threshold proton-nucleus collisions
Zetenyi, M.; Barz, H.-W.
Abstract
We study the cross section of phi-meson production in proton-nucleus collisions. The decay width of the phi-meson is affected by the change of the masses of the phi, K+, K- mesons in medium. A strong attractive K_ potential leads to a broadening of the phi-meson, which results in a measurable change of the behavior of the cross section as a function of the target mass.
Keywords: proton-nucleus collisions; in-medium effects; antikaon potential
