[SLAC] [SLAC Pubs and Reports] SLAC-PUB-7453Searching for Anomalous tau neutrino W Couplings Abstract The capability of current and future measurements at low and high energy $e^+e^-$ colliders to probe for the existence of anomalous, CP conserving, $\tau \nu W$ dipole moment-type couplings is examined. At present, constraints on the universality of the tau charged and neutral current interactions as well as the shape of the $\tau \to \ell$ energy spectrum provide the strongest bounds on such anomalous couplings. The presence of these dipole moments are shown to influence, \eg, the extraction of $\alpha_s(m_\tau^2)$ from $\tau$ decays and can lead to apparent violations of CVC expectations. (Equations render on Windows, Mac OS, AIX, Linux, Solaris, and IRIX with the techexplorer plug-in.)
