The Chirally Normalized Vector Meson Dominance Model and Semihadronic Tau Decays


We discuss and test the assumptions of the chirally normalized vector meson dominance model (CN-VMD), as it is used for tau decays. We compare the CN-VMD amplitudes with those using on-shell couplings, derived directly from experimental data. We discuss in detail the 3π, KKπ and 2π final states. We suggest that the true values for the K1 widths might be… (More)
