The Joint Extraction of m_s and V_us From Hadronic Tau Decay Data
K. Maltman, C. E. Wolfe
We discuss the simultaneous determination of m_s and V_us from flavor-breaking hadronic tau decay sum rules, focussing on weight choices designed to better control problems associa…
OPE Constraints and the Leading Order Hadronic Contribution to (g-2)_mu
Kim Maltman
OPE constraints are studied as a means of distinguishing between the versions of the I=1 vector spectral function extracted from (i) inclusive I=1 hadronic electroproduction cross-…
V_us From Hadronic Tau Decays
K. Maltman, C. E. Wolfe
We study extractions of |V_us| based on finite energy sum rule (FESR) analyses of hadronic tau decay data. We show (i) that the ``(0,0) spectral weight'' implementation (proposed p…
V_us From Hadronin Tau Decays
Kim Maltman, C. E. Wolfe
We study the reliability of extractions of |V_{us}| based on flavor-breaking hadronic tau decay sum rules. The ``(0,0) spectral weight'', proposed previously as a favorable candida…
