Bethe-salpeter equation studies of SU{sub f}(3) mesons

The spectroscopy and weak decays of mesons composed of u, d, and s quarks is being studied using a separable approximation to the quark-quark scattering kernel. This is a first, simple step towards an extraction of the form of the quark-quark interaction at small space-like-q{sup 2} directly from experimental observables. The kernel is obtained by using a separable approximation to invert the DSE for the quark propagator. The quark propagator used is the phenomenologically-efficacious, confining model form derived in the study of F{sub {pi}}(q{sup 2}), which is described above. Preliminary results are encouraging, showing that pion observables can indeed be used as a sensitive probe of the effective quark-quark interaction in the infrared.
