Inclusive χc and b-quark production in p¯p collisions at √s =1.8 TeV Academic Article uri icon

abstract

  • We report the full reconstruction of χc mesons through the decay chain χc→J/ψ γ, J/ψ→μ+μ-, using data obtained at the Collider Detector at Fermilab in 2.6±0.2 pb-1 of p̄p collisions at s =1.8 TeV. This exclusive χc sample is used to measure the χc-meson production cross section times branching fractions. We obtain σ×B=3.2±0.4(stat)-1.1+1.2(syst) nb for χc mesons decaying to J/ψ with pT>6.0 GeV/c and pseudorapidity η<0.5. From this and the inclusive J/ψ cross section we calculate the inclusive b-quark cross section to be 12.0±4.5 μb for pTb>8.5 GeV/c and <1. © 1993 The American Physical Society.
