Abstract: The decays χ c 1 → J / ψ μ + μ − and χ c 2 → J / ψ μ + μ − are observed and used to study the resonance parameters of the χ c 1 and χ c 2 mesons. The masses of these states are measured to be m ( χ c 1 ) = 3510.71 ± 0.04 ( stat ) ± 0.09 ( syst )     MeV and m ( χ c 2 ) = 3556.10 ± 0.06 ( stat ) ± 0.11 ( syst )     MeV , where the knowledge of the momentum scale for charged particles dominates the systematic uncertainty. The momentum-scale uncertainties largely cancel in the mass difference m ( χ c 2 ) − m ( χ c 1 ) = 45.39 ± 0.07 ( stat ) ± 0.03 ( syst )     MeV . The natural width of the χ c 2 meson is measured to be Γ ( χ c 2 ) = 2.10 ± 0.20 ( stat ) ± 0.02 ( syst )     MeV . These results are in good agreement with and have comparable precision to the current world averages.
