Z0 Line Shape Fit

  •  Institute of High Energy Physics,Academia Sinica,Beijing 100039

  • We state a fitting method of the Z0 line shape.We discuss the radiative corrections for calculating the theoretical cross sections of e+e－→ff on Z0 resonance,and compare the results from different programs.The systematic measurement errors are taken into account in our fitting.As an example,we fit the τ+τ－ channel Z0 line shape to determine some Z0 parameters.

Abstract: We state a fitting method of the Z0 line shape.We discuss the radiative corrections for calculating the theoretical cross sections of e+e－→ff on Z0 resonance,and compare the results from different programs.The systematic measurement errors are taken into account in our fitting.As an example,we fit the τ+τ－ channel Z0 line shape to determine some Z0 parameters.
