Abstract

The resonance parameters of the χ_c0, the 1³P₀ state of charmonium, have been measured at the Fermilab Antiproton Accumulator in the reaction pp → χ_c0 → γJ/ψ → γ(e⁺e^-). A large data sample collected during the year 2000 run yields the results: M(χ_c0) = 3415.4±0.4±0.2 MeV/c², γ(χ_c0) = 9.8±1.0±0.1 MeV, B(χ_c0 → pp) × B(χ_c0 → γJ/ψ) × B(J/ψ → (e⁺e^-)) = (1.61±0.11±0.08) × 10^-7. Taking B(χ_c0 → γJ/ψ) and B(J/ψ → e⁺e^-) from the literature, we obtain B(χ_c0 → pp) = (4.1±0.3_-0.9⁺¹⁶) × 10^-4 and γ(χ_c0 → pp) = (4.0±0.4_-0.9^+1.6) keV.
