Observation of φφ production in the reaction at 1.4 GeV / c incident momentum
1995
Physics Letters B
The JETSET (PS202) experiment at CERN{LEAR searches for hadronic resonances by means of in-ight a n tiproton{proton annihilations in the reaction pp . In order to obtain sucient luminosity and good nal-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 pp 4K at 1.4 GeV/c incident p momentum, and we present the rst experimental observation of a strong signal in this reaction.
