Descrizione

In this talk we will introduce an accurate dispersive parametrization of the two K_{l3} form factors and discuss three applications to the analysis of K_{e3} and K_{mu3} measurements: the prediction of the branching ratios K_{mu3}/K_{e3}, the extraction of |f_+(0)V_{us}| and finally the possible measurement of m_d - m_u induced isospin breaking asymmetry.
