DESCRIPTION:We present the new hadronic currents implemented in the Monte 
 Carlo generator TAUOLA\, which is the standard library for analysing tau l
 epton measurements: both in high-energy experiments (such as LHC) and in t
 he heavy-flavour factories (BaBar and Belle). The theoretical approach to 
 obtain the relevant form factors is based on their appropriate low-energy 
 limit given by Chiral Perturbation Theory\, their QCD-ruled short-distance
  behaviour and the large number of colours limit of QCD\, whose modelizati
 on within our framework is discussed. The new set of form factors covers m
 ore than 88% of the hadronic tau decay width. We hope that\, through confr
 ontation with the data\, improvements of the present form factors and addi
 tion of some of the most important missing channels\, it will become a hel
 pful tool in order to extract valuable physical information on many intere
 sting observables.\n\nhttps://indico.ific.uv.es/event/1862/
