EFFECTIVE LAGRANGIAN FOR PSEUDOSCALAR MESONS FROM LINEAR SU(3)×SU(3) SIGMA MODEL WITH VECTOR AND AXIAL MESONS
Keyword(s):
The effective Lagrangian for pseudoscalar meson octet including terms up to fourth order in momenta and masses is derived from a linear sigma model with vector and axial mesons. The mass of scalar meson nonet 720±75 MeV ensures a good fit of coefficients in effective Lagrangian with values derived from experiment.
