Study of predominant hadronic modes of $\tau$-lepton using a Monte Carlo generator TAUOLA

Abstract

TAUOLA is a Monte Carlo generator dedicated to generating tau-lepton decays and it is used in the analysis of experimental data both at B-factories and LHC. TAUOLA is a long-term project that started in the 90's and has been under development up to now. In this note we discuss the status of the predominant hadronic tau-lepton decays into two ($Br\simeq 25.52\%$) and three pions ($Br\simeq 18.67\%$).
