Abstract
- By using the new result of τ-mass from Beijing spectrometer and the data of τ → 5πντ from ARGUS, the upper limit of ντ-mass of 30 MeV is obtained at 95% confidence level. The upper limit of the ψτ-mass could be largely reduced if a high resolution detector is used in the improved Beijing electron positron collider, which is under discussion.
