摘要：
The dimensionless form factors f(s)(0), g(0), h(0) and lambda which account for almost all the microscopic details of the K(l4) decay are computed in an integrated QCD oriented Bethe-Salpeter framework, where all the free parameters involved in the formalism are fixed by the best fit with the Hadron mass spectroscopy, so that for the present evaluation we have a parameter-free model. The values of the form factors so obtained are in good agreement with the experimental values and the agreement is comparable with the recent similar calculations using large-N(c) limits in chiral QCD theory.
