| 英文摘要 | Abstract a detailed theoretical derivation of the cross sections of e+e? → e+e? and e+e? → μ+μ? around the j/ψ resonance is reported. the resonance and interference parts of the cross sections, related to j/ψ resonance parameters, are calculated. higher-order corrections for vacuum polarization and initial-state radiation are considered. an arbitrary upper limit of radiative correction integration is involved. full and simplified versions of analytic formulae are given with precision at the level of 0.1% and 0.2%, respectively. moreover, the results obtained in the paper can be applied to the case of the ψ(3686) resonance. |
