CERN-LEP. Measurement of the cross sections and forward-backward asymmetries of lepton pair production in E+ E- interactions around the Z0 peak. The data come from the energy scan during the 1993-1995 LEP running period where the energies were 1.76 GeV below and above the Z0 peak (in addition to at the peak) and the 1994 single energy run near the Z0 peak. In addition the dimuon events with a photon radiated in the initial state (ISR data) have been used to probe cross sections and asymmetries down to PETRA energies. Model independent fits to all DELPHI lineshape and asymmetry data from 1990 to 1995 give the following values of the resonance parameters. MZ = 91.1863 +- 0.0028 GeV. Gamma Z = 2.4876 +- 0.0041 GeV. SIGMA0 = 41.578 +- 0.069 nb. Rl = 20.730 +- 0.060. ASYM0(NAME=AFB) = 0.0187 +- 0.0019.

CERN-LEP实验：针对Z⁰玻色子峰附近的正电子-负电子（E⁺E⁻）相互作用中轻子对产生的截面与前后不对称性展开测量。本数据集包含1993年至1995年LEP运行周期内的能量扫描实验数据，以及1994年在Z⁰峰附近开展的单次能量运行实验数据；其中1993-1995年的能量扫描实验所采用的对撞能量分别为Z⁰峰能量上下1.76 GeV，同时包含峰位能量。此外，研究还利用初态辐射（Initial State Radiation，ISR）光子的双μ子事件（ISR数据）来探测低至PETRA能量区间的截面与不对称性参数。对1990年至1995年间DELPHI实验组获取的全部共振线型与不对称性数据开展无模型拟合后，得到以下共振参数数值：M_Z=91.1863±0.0028 GeV，Γ_Z=2.4876±0.0041 GeV，σ₀=41.578±0.069 nb，R_ℓ=20.730±0.060，ASYM₀（命名为AFB）=0.0187±0.0019。
