Abstract

The new parameterization of form factors developed for 4pi channels of the tau lepton decay and based on Novosibirsk data on e+e- -> 4pi has been coded in a form suitable for the TAUOLA Monte Carlo package. Comparison with results from TAUOLA using another parameterization, i.e. the CLEO version of 1998 is also included.
