Alpha_s from hadronic tau decay data
Kim Maltman, Tzahi Yavin
We discuss the extraction of alpha_s using isovector hadronic tau decay data and sum rules constructed specifically to suppress contributions associated with poorly known higher di…

Status of the Hadronic Tau Determination of V_us
K. Maltman, C. E. Wolfe, S. Banerjee +2
We update the extraction of |V_{us}| from hadronic tau decay data in light of recent BaBar and Belle results on the branching fractions of a number of important strange decay modes…

Alpha_s(M_Z) from hadronic tau decays
K. Maltman, T. Yavin
We perform an extraction of alpha_s based on sum rules involving isovector hadronic tau decay data. The particular sum rules employed are constructed specifically to suppress contr…
