| 英文摘要 | The decays chi(c1) -> j/psi mu(+)mu(-) and chi(c1) -> j/psi mu(+)mu(-) are observed and used to study the resonance parameters of the chi(c1) and chi(c2) mesons. the masses of these states are measured to be m(chi(c1)) = 3510.71 +/- 0.04(stat) +/- 0.09(syst) mev and m(chi(c2)) = 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(chi(c2)) - m(chi(c1)) = 45.39 +/- 0.07(stat) +/- 0.03(syst) mev. the natural width of the chi(c2) meson is measured to be gamma(chi(c2)) = 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. |
