Determination of the LEP center-of-mass energy from $Z\gamma$ events: Preliminary

Radiative returns to the Z resonance (Zgamma events) provide a method to determine the centre-of-mass energy of the high energy e+e- colliders and already at LEP2. The method is applied for the data collected with the ALEPH detector in 1997 at 181-184 GeV, using $e^+e^- \to \gamma Z \to hadrons$ eve...
