CHARGE FORM-FACTOR OF PI-MESONS AND K-MESONS

The charge form factor of pi and K mesons is evaluated adopting a rela tivistic constituent quark model based on the light-front formalism. T he relevance of the high-momentum components of the meson wave functio n, for values of the momentum transfer accessible to CEBAF energies, i s illustrated. The predictions for the elastic form factor of pi and K mesons are compared with the results of different relativistic approa ches, showing that the measurements of the pion and kaon form factors planned at CEBAF could provide information for discriminating among va rious models of the meson structure.
