The ratios of the numbers of Z bosons decaying to e+e−, mu+mu- and tau+tau- pairs to the number decaying to hadrons have been measured. The branching ratios and partial widths for each channel were determined and found to be equal, consistent with lepton universality.

Abstract
The ratios of the numbers of Z bosons decaying to e+e−, mu+mu- and tau+tau- pairs to the number decaying to hadrons have been measured. The branching ratios and partial widths for each channel were determined and found to be equal, consistent with lepton universality.File in questo prodotto:
