Broad Program

The Belle II experiment is an upgrade of the Belle detector and will operate at the SuperKEKB energy-asymmetric e^+e^-e+e− collider. The accelerator has already successfully completed the first phase of commissioning and first electron positron-collisions in Belle II were observed in April 2018. The design luminosity of SuperKEKB is 8x10^{35}35 cm^{-2}−2s^{-1}−1 and the Belle II experiment aims to record 50 ab^{-1}−1 of data. Belle II has a broad program of \tauτ physics, in particular, precision measurements of Standard Model parameters and searches of lepton flavor and lepton number violations, benefiting from the large cross-section of the pairwise \tauτ lepton production in e^+e^-e+e− collisions. In this talk, we will review the \tauτ lepton physics program of Belle II.

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.
