Description
The width of the decay τ→f1 πντ has recently been measured by the BaBar experiment. The estimation of this width is given in the framework of the NJL model with the axial-vector mesons. Prediction is in agreement with experimental data. It is shown that the π- a1 transition contribution plays an important role and allows us to bring the NJL prediction to the data. (orig.)
