title = "Events with large missing transverse energy at the cern collider: I.W→τν decay and test of τμe universality at Q2=mw2",
abstract = "We report results based on a sample of events with large missing transverse energy corresponding to 715 nb-n of data from the UA1 experiment at the CERN proton-antiproton collider. High transverse-momentum tau-leptons from W decays are observed for the first time through their semi-hadronic decay modes and associated missing transverse energy. The measured relative rates of W→eν, W→μν, and W→τν provide the first direct tests of the electron-muon-tau universality of the weak charged couplings at Q2=mw2. We determine gτ ge=1.01±0.09±0.05 and gμ ge=1.05±0.07±0.08.",
