The number of neutrinos and the Z line shape
Thanks to a precise calibration and monitoring of the LEP beam energy the Z resonance line shape has been precisely measured, hence permitting accurate determinations of the Z mass and width. A large effort was spent on experiments for the measurement of the LEP luminosity, enabling the number of ne...
