etau and mutau was made with the DELPHI detector at LEP, using a sample
corresponding to an integrated luminosity of 11.2 pb-1. The number of
candidates was consistent with the estimated background. The upper limit
on the branching ratio (at 95% confidence level) for Z0 –> emu was 3.2
x 10(-5), for Z0 –> etau was 10.8 x 10(-5) and for Z0 –> mutau was
13.5 x 10(-5)."
