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