Abstract

Radiative returns to the Z resonance (Zγ events) are used to determine the LEP2 centre-of-mass energy from the data collected with the ALEPH detector in 1997. The average centre-of-mass energy is measured to be: ECM = 182.50 ± 0.19 (stat.) ± 0.08 (syst.) GeV in good agreement with the precise determination by the LEP energy working group of 182.652 ± 0.050 GeV. If applied to the measurement of the W mass, its precision translates into a systematic error on MW which is smaller than the statistical error achieved from the corresponding dataset. © 1999 Elsevier Science B.V.
