The decay in the Nambu-Jona-Lasinio model
Abstract
The width of the decay 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 transition contribution plays an important role and allows us to bring the NJL prediction to the data.
