Charged particle pair production associated with a lepton pair in Z decays. Indication of an excess in the tau channel
Description
In a sample of 200.000 Z decays, events with two leptons and an additional pair of charged particles are studied. The 35 events found show a possible excess in the tau channel compared with the expectation from electroweak processes. The features of the events are consistent with radiation of virtual photons.
