Abstract
We report the full reconstruction of mesons through the decay chain →J/ψ γ, J/ψ→ , using data obtained at the Collider Detector at Fermilab in 2.6±0.2 of p¯p collisions at √s =1.8 TeV. This exclusive sample is used to measure the -meson production cross section times branching fractions. We obtain σ×B=3.2±0.4(stat(syst) nb for mesons decaying to J/ψ with >6.0 GeV/c and pseudorapidity ‖η‖8.5 GeV/c and ‖‖<1.
