The Chirally Normalized Vector Meson Dominance Model and Semihadronic Tau Decays
نویسنده
چکیده
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 larger than those quoted in the Review of Particle Physics.

Predictions based on the chirally normalized vector meson dominance model for decay rates and distributions of τ decays into Kππντ final states are discussed. Disagreements with experimental results can be traced back to the K1 widths. Hadronic τ decays into final states with kaons can provide detailed information about low energy hadron physics in the strange sector. Predictions for final stat...
متن کاملStructure Functions in Semihadronic Tau Decays
We review a variety of topics related to hadronic structure functions in exclusive semihadronic tau decays. We introduce the concept of structure functions and summarize the most important concepts. We then calculate the decay τ → 3πντ for very small hadronic invariant mass to one loop in Chiral Perturbation Theory. New interesting features emerge with respect to the known results at tree level...
متن کاملSystematics of Large Axial Vector Meson Production in Heavy Flavor Weak Decays
Large branching ratios observed for D and B decays to final states containing the a1(1260) ± are comparable to those for corresponding decays to states containing a charged pion or a charged ρ, and much larger than those for all other decays. Implications are discussed of a “vector-dominance model” in which a W is produced and immediately turns into an axial vector, vector or pseudoscalar meson...

We present an approach which allows for modifications of the (minimal) analytic QCD model of Shirkov, Solovtsov et al.. The discontinuity function of the (minimal) analytic QCD coupling parameter is changed at the low time-like momenta by a simple ansatz motivated by the vector meson dominance for the vector channel of the e + e − hadronic decay ratio RV (s). In this way, the additional low ene...
متن کاملh\pgg decay within a chiral unitary approach
We improve the calculations of the h→p0gg decay within the context of meson chiral Lagrangians. We use a chiral unitary approach for the meson-meson interaction, thus generating the a0(980) resonance and fixing the long standing sign ambiguity on its contribution. This also allows us to calculate the loops with one vector meson exchange, thus removing a former source of uncertainty. In addition...
