Description
A continuum approach to the pion, kaon and pseudoscalar $ss$ bound-state problems is used to reveal their electromagnetic structures. For these systems, when used with parton disbribution amplitudes appropriate to the scale of experiment,
Standard Model hard-scattering formulae are accurate to within 25 % at medium momentum transfers. The large Q^2 evolution is accurately described by the hard scattering formulae. These results should prove useful in Lattice simulation and in planning next-generation expriments.
