摘要 由分析散布事件 e <SUP>+</SUP 的大角度的 Bhabha > e <SUP></SUP>() e <SUP>+</SUP > e <SUP></SUP>和 diphoton 事件 e <SUP>+</SUP > e <SUP></SUP>()为数据,集合与升级的北京在 center-of-mass ( c.m )收集了在 2.2324 和 4.5900 GeV (总共的 131 个精力点)之间的精力在北京电子正电子 Collider ( BEPCII )的分光计( BESIII ),综合光明个别地在不同 c.m 精力被测量了。结果是为 R 价值和 J/ 回声参数大小的重要输入。 By analyzing the large-angle Bhabha scattering events e^+e^- → (γ)e^+e^- and diphoton events e^+^e- → (γ)γγ for the data sets collected at center-of-mass (c.m.) energies between 2.2324 and 4.5900 GeV (131 energy points in total) with the upgraded Beijing Spectrometer (BESIII) at the Beijing Electron-Positron Collider (BEPCII), the integrated luminosities have been measured at the different c.m. energies, individually. The results are important inputs for the R value and J/ψ resonance parameter measurements.
