Electroweak properties of light mesons in relativistic hamiltonian dynamics

الأصل · EN

The calculation of lepton decay constants and electromagnetic form factors of pion and kaon is performed in the framework of relativistic hamiltonian dynamics. The different model wave function is used. Wave function parameters are fixed from fit of mean square radius of meson. The internal quark structure is taken into account by electromagnetic quark form factor and quark anomalous magnetic moment. The pion and kaon form factors depend only weakly on model wave function. Strong dependence of these values on quark anomalous magnetic moment is obtained in the transfer momentum region of CEBAF experiments.
