SEMINAR - Muon g-2 from tau and e+e- data and rho-gamma mixing

Thursday February 14th 2013, 2:30 pm - Seminar room

Speaker: Fred Jegerlehner (DESY, Zeuthen)

Abstract: The energy dependence of the rho-gamma mixing in the 2x2 gamma-rho propagator matrix, is shown to be able to account for the e^+e^- vs. tau spectral function discrepancy.

Consequences for the muon g-2 are discussed. Extensions based on the Resonance Lagrangian Approach (specifically the HLS model) are also discussed.
