We report recent measurements on τ leptons obtained by the BABAR collaboration using the entire recorded sample of electron-positron collisions at and around the Υ(4S) (about 470fb-1). The events were recorded at the PEP-II asymmetric collider at the SLAC National Accelerator Laboratory. The measurements include high multiplicity τ decay branching fractions with 3 or 5 charged particles in the final state, a search for the second class current the τ decay τ → πη′ν, τ branching fractions into final states containing two KS mesons, [Formula: see text], with h = π, K, and preliminary measurements of hadronic spectra of τ decays with three hadrons (τ- → h-h+h-ντ decays, where h = π, K). The results improve the experimental knowledge of the τ lepton properties and can be used to improve the precision tests of the Standard Model.

The BESIII is a general-purpose experiment for studying electron-positron collisions at BEPCII which is located at IHEP, Beijing, China. It works in the τ-charm region mainly. Several world’s largest samples in this region had been collected. The BESIII DQM is a lightweight online data quality monitoring (DQM) solution at BESIII. It uses the full offline reconstruction software to reconstruct a part of data for real-time monitoring the data quality. The document gives an overview of the BESIII DQM system, including the framework, main components and data flow. The DQM system separates online DAQ and offline software environment as much as possible and is easy to expand.
