Description

We present improved determinations of |Vus| with tau decays relying on the HFLAV tau branching fractions global fit results. The HFLAV results are to be included in the 2019 HFLAV report and use the recent new BaBar measurements of:

  • the branching fractions of the processes $\tau^{-}\to K^{-} n\pi^{0}\nu_\tau$ with n=1,2,3 and $\tau^{-}\to \pi^{-} n\pi^{0}\nu_\tau$ with n=3,4;

  • the branching fraction $\tau^{-}\to K^{-}\bar{K}_{S}^{0} \nu_\tau$;

which were not included in the Spring 2017 HFLAV report.
