Issues in the Extraction of m_s and V_us from Hadronic Tau Decay Data
arXiv:hep-ph/0412326 · doi:10.1016/j.nuclphysbps.2005.02.009
Abstract
Various complications encountered in the process of attempting to extract the basic Standard Model parameters, m_s and V_us, from hadronic tau decay data are discussed. Preliminary results for V_us, based on sum rules displaying good convergence and stability, are also presented.
