TL;DR
This paper details an upgrade to the TAUOLA Monte Carlo generator incorporating Resonance Chiral Theory for tau decay modes, with initial parameter fitting based on BaBar data for three-pion decays.
Contribution
It introduces a partial upgrade to TAUOLA using Resonance Chiral Theory and provides initial fit parameters based on experimental data.
Findings
Resonance Chiral Theory effectively models tau decay modes.
Initial fit parameters align with BaBar experimental data.
88% of tau's hadronic width is covered by these modes.
Abstract
We present the results of a partial upgrade to the Monte Carlo event generator TAUOLA using Resonance Chiral Theory for the two and three meson final states. These modes account for 88% of total hadronic width of the tau meson. The first results of the model parameters have been obtained using Preliminary BaBar data for the three pion mode.
