Electromagnetic form factors of pion and rho in the three forms of relativistic kinematics

摘要: The electromagnetic form factors of the pi and rho are obtained using three forms relativistic kinematics, instant form, point (light) front form. Simple representations mass operator together with single quark currents employed all forms. Poincare covariant current operators generated by dynamics from single-quark that under kinematic subgroup. Front allow to reproduce available data for pion factor. On other hand is not able qualitatively experimental reasonable values wave function parameters. For factors, provide a consistent picture. results do depend appreciably on used.
