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++1^{++} (a1/f1a_1/f_1) axialvector charge eigenstate masses are unaltered whereas the 1+1^{+-} (b1/h1b_1/h_1) axialvector meson mass is raised.
