Abstract
We present the first calculations of the electromagnetic form factors of and within the framework of the Covariant Spectator Theory (CST). This first exploratory study concentrates on the sensitivity of the form factors to the strength of the scalar meson-nucleon off-shell coupling, known from previous studies to have a strong influence on the three-body binding energy. Results presented here were obtained using the complete impulse approximation (CIA), which includes contributions of relativistic origin that appear as two-body corrections in a nonrelativistic framework, such as “Z-graphs,” but omits other two and three-body currents. We compare our results to nonrelativistic calculations augmented by relativistic corrections of .
