Chiral dynamics andK l4 form factors

  • Published:
Zeitschrift für Physik A Hadrons and nuclei

Abstract

The axial vector form factors for the decayK l4 are studied in the context of effective Lagrangian invariant under chiralSU(3)⊗SU(3) symmetry. The hadronic part of the process is converted into a scattering process by using a field-current identity and the amplitude in turn is calculated by assuming pole dominance. The relations for the form factors thus obtained are (in some soft limit) consistent with those of current algebra and Veneziano model.
