J/psi resonance production in 125-GeV/c anti pN and. pi. /sup -/N interactions

Conference ·
OSTI ID:6768651
We present preliminary results for the production of the J/psi resonance in 125 GeV/c antiproton and pi minus-nucleon interactions as determined from an analysis of 9100 antiproton and 28,750 pi minus induced J/psi's. Total cross sections (x/sub f/ > 0) for J/psi production by both particle types are determined and the ratio of sigma/sub anti p//sigma/sub ..pi..//sup -/ is found to be 0.88 +- 0.05. Differential cross sections for J/psi production are given as a function of x/sub F/ and p/sub T/. The ratio of the d sigma/dx/sub F/ cross sections as a function of x/sub F/ is shown.
