【 摘 要 】

We recapitulate the aspects of Dyson-Schwinger equation (DSE) studies relevant topseudoscalar mesons: lattice confirmation of the DSE prediction that propagators arenonperturbatively dressed in the infrared; and exact results, e.g., the leptonic decayconstant vanishes for every pseudoscalar meson except the pion in the chiral limit.
