    Chiral Lagrangians and pion-field redefinition

    An explicit solution of the differential equation for Weinberg’s class of chiral Lagrangians, with arbitraryf(π 2), is given here. On the contrary, for any given symmetry-breaking term the explicit solution of th...

    Nakanishi representation and unitarity condition

    The explicit forms of the kernels appearing in the elastic unitarity condition are derived for the Nakanishi representation of scattering amplitude.
