It provides a comprehensive overview of tau mass measurements and evaluates the experimental limits on lepton universality violations.
Findings
Tau mass measurements achieved with high precision.
Current data supports lepton universality within experimental uncertainties.
Identifies areas for improved precision in future experiments.
Abstract
The report reviews the measurements of the tau lepton parameters. The tau mass measurements at the KEDR detector as well as at the B-factories are considered in more details. The present limitations on the lepton universality are discussed.
