Duality violations in hadronic tau decays and the value of alpha_s
Diogo Boito, Oscar Cata, Maarten Golterman +4
We discuss the quantitative impact of duality violations on the determination of the strong coupling constant from hadronic tau decays, based on a preliminary analysis of OPAL data…
Hadronic Tau Decay Based Determinations of |V_us|
Kim Maltman
I review sum rule determinations of |V_us| employing hadronic tau decay data, taking into account recent HFAG updates of exclusive tau branching fractions and paying special attent…
Consequences of the BaBar e^+e^- --> pi^+pi^- Measurement for the Determination of Model-Dependent rho-omega Mixing Effects in Pi_{ρω}(m_ρ^2) and (g-2)_mu
C. E. Wolfe, K. Maltman
We update our analysis of rho-omega mixing effects in the pion form factor to incorporate the recently published BaBar e^+e^- --> pi^+π^- cross-sections. The implications for tau-d…
V_us (and m_s) From Hadronic Tau Decays
K. Maltman, C. E. Wolfe
We describe how complications encountered in the extraction of V_us from flavor-breaking hadronic tau decay sum rules, in particular those associated with the slower than previousl…
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…
