Abstract
In the last two years substantial progress for the simulation of the process: τ−→π−π+π−ντ by the Monte Carlo generator TAUOLA was achieved. It is related to a new parameterization of the corresponding hadronic current based on the Resonance Chiral Lagrangian and the recent availability of the unfolded distributions from the BaBar Collaboration analysis for all invariant hadronic masses. The theoretical model parameters were fitted to the one-dimensional distributions provided by the BaBar Collaboration and results of the fit are discussed. A set of the hadronic currents for other final states with two and three pseudo-scalars is also installed in TAUOLA and the preliminary results for fitting K+K−π− and π0π− to BaBar and Belle data are presented.
