Title: Current Status of inclusive hadronic tau determinations of |V_us|

Abstract

We review the status of the determination of \vert V_{us}\vert | V u s | from both flavor-breaking finite-energy sum rules based on inclusive non-strange and strange hadronic \tau τ decay data and the recent lattice-based analysis of inclusive strange hadronic \tau τ decay data. In particular, we update the results from these analysis frameworks taking into account recent improvements to a number of strange branching fractions reported by HFLAV at CKM2018 and this meeting. We find that inclusive \tau τ decay data yields results for \vert V_{us}\vert | V u s | compatible within errors with the expectations of three-family unitarity.
