Observation of φφ production in the reaction overlinepp → 4K ± at 1.4 GeV / c incident overlinep momentum
Abstract
The JETSET (PS202) experiment at CERN-LEAR searches for hadronic resonances by means of in-flight antiproton-proton annihilations in the reaction overlinepp → φφ . In order to obtain sufficient luminosity and good final-state mass resolution, this experiment uses an internal hydrogen-cluster jet target intersecting the LEAR antiproton beam. We report on the study of the reaction overlinepp → 4K ± at 1.4 GeV / c incident p¯ momentum, and we present the first experimental observation of a stro φφ signal in this reaction.
