J/ψ production in pp̄ collisions at √s = 1.8 TeV
- Abstract:
-
We have studied J/ψ production in pp̄ collisions at √s = 1.8 TeV with the DØ detector at Fermilab using μ+/μ- data. We have measured the inclusive J/ψ production cross section as a function of J/ψ transverse momentum, pT. For the kinematic range pT > 8 GeV/c and |η\ < 0.6 we obtain σ(pp̄ → J/ψ + X) ·Br(J/ψ → μ+μ-) = 2.08 ± 0.17(stat) ± 0.46(syst) nb. Using the muon impact parameter we have estimated the fraction of J/ψ mesons coming from B meson decays to be fb = 0.35 ± 0.09(stat)±0.10(...
