We present results of a hybrid-bubble-chamber experiment examining the reaction π+p→π+pK+K− at an incident momentum of 11.46 GeV/c. The total cross section for this channel is determined to be 87.2±6.4 μb. A partial-wave analysis of the K+π+K− system reveals no unambiguous evidence of resonant activity, although mass enhancements are noted in the JP=0− κ¯K+ (S wave), JP=2− fπ (S wave), and JP=2−, K¯*0(892)K+ (P wave). This is the first published report of the relative phases of the waves seen in this reaction. We comment on the influence this channel may have on A1 and A3 production.

A measurement is reported of charged multiplicity distributions of high-mass diffractive π±, K±, and p± states produced in 100 and 200 GeV/c hadron-proton collisions, h+p→X+p. The distributions are described well by a Gaussian function that depends only on the available mass M=Mx−Mh, has a maximum at n0≅2M12, and a peak-to-width ratio n0D≅2.
