Recent Developments in the Bethe-Salpeter Description of Light Mesons
Abstract
Results for the light meson mass spectrum from a Bethe-Salpeter approach are presented. The results obtained in the standard framework are Poincar\'e covariant and compare favourably with lattice results. Using a more sophisticated scheme, the pseudoscalar, vector and 1++ (a1/f1) axialvector charge eigenstate masses are unaltered whereas the 1+- (b1/h1) axialvector meson mass is raised.
