A Poincaré Covariant Current Operator for Low and High Energy Phenomena
F. M. Lev, E. Pace, G. Salme`
Abstract
Within front-form dynamics and in the Breit frame where initial and final three-momenta of the system are directed along the z axis, Poincaré covariance constrains the current operator only through kinematical rotations around the z axis. Therefore, in this frame the current can be taken in the one-body form. Applications to deep inelastic structure functions in an exactly solvable model and to the deuteron magnetic form factor are presented.
