EnglishWe report recent measurements on tau leptons obtained by the BABAR collaboration using the entire recorded sample of electron-positron collisions at and around the Upsilon(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 tau decay branching fractions with 3 or 5 charged particles in the final state, a search for the second class current the tau decay tau rarr pieta'nu, tau branching fractions into final states containing two K S mesons, tau rarr h - K S0 K S0 (pi 0) nu tau, with h = pi, K, and preliminary measurements of hadronic spectra of tau decays with three hadrons (tau - rarr h -h +h -nu tau decays, where h = pi, K). The results improve the experimental knowledge of the tau lepton properties and can be used to improve the precision tests of the Standard Model.

| Abstract: | We report recent measurements on tau leptons obtained by the BABAR collaboration using the entire recorded sample of electron-positron collisions at and around the Upsilon(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 tau decay branching fractions with 3 or 5 charged particles in the final state, a search for the second class current the tau decay tau rarr pieta'nu, tau branching fractions into final states containing two K S mesons, tau rarr h - K S0 K S0 (pi 0) nu tau, with h = pi, K, and preliminary measurements of hadronic spectra of tau decays with three hadrons (tau - rarr h -h +h -nu tau decays, where h = pi, K). The results improve the experimental knowledge of the tau lepton properties and can be used to improve the precision tests of the Standard Model. |
