Abstract

The total cross section of the reaction pp → ppK⁺K^- has been determined for proton-proton reactions with p_beam = 3.67GeV/c. This represents the first cross section measurement of the pp → ppK^-K⁺ channel near threshold, and is equivalent to the inclusive pp → ppK^-X cross section at this beam momentum. The cross section determined at this beam momentum is about a factor 20 lower than that for inclusive pp → ppK⁺X meson production at the same CM energy above the corresponding threshold. This large difference in the K⁺ and K^- meson inclusive production cross sections in proton-proton reactions is in strong contrast to cross sections measured in sub-threshold heavy ion collisions, which are similar in magnitude at the same energy per nucleon below the respective thresholds.
