Abstract
The reactions π+ p→π+(K + K − π+ π− p andpp→p(K + K − π+ π−)p where the (K + K − π+ π−) system is centrally produced have been studied at 85 GeV/c. 48% of the final state proceeds through single or double vector meson resonant production i.e.,K *0(890) (37%), ϕ (4%),ρ 0 (7%). Evidence is found for associatedK *0 (890)\(\bar K\) *o (890) production (6.4±1.1%) with a cross section ten times higher than that found for associated ϕ ϕ production in the same experiment.
