    Oral contribution

    τ lepton is a fundamental particle in the standard model, and its mass is a very sensitive quantity in testing the lepton-universality.
    BESIII gave the most precise τ mass value in a single measurement in 2014, but the accuracy is still much lower than those of electron and muon.
    In order to improve the accuracy of τ mass measurement, more than 130 pb-1 τ mass scan data were collected in...

  4. 102. Status and prospects for tau property measurements at Belle II
    Dr Michel Hernandez Villanueva (DESY)

    Oral contribution

    The Belle II experiment is a substantial upgrade of the Belle detector, operating at the SuperKEKB energy-asymmetric e+e− collider. The design luminosity of the machine is 8 × 10^35 cm−2s−1, and the Belle II experiment aims to record 50 ab−1 of data, a factor of 50 more than its predecessor. From February to July 2018, the machine has completed a commissioning run and the main operation of...

  5. 121. Third order correction to the muon lifetime
    Dr Matteo Fael (KIT Karlsruhe)

    Tau2021 Abstracts
    Oral contribution

    In this talk I will present the calculation of the QED third order correction to the muon lifetime. This result is obtained in the so-called heavy daughter approximation, i.e. the decay rate is computed in the limit of equal muon and electron masses which yields crucial simplifications in the evaluation of multi-loop Feynman diagrams. Despite the electron being about 207 times lighter that the...
