THE DEUTERON ELECTRODISINTEGRATION NEAR-THRESHOLD IN THE LIGHT-FRONT DYNAMICS

The deuteron electrodesintegration near threshold is a process which i s known to be quite sensitive to-various physical inputs such as NN wa ve functions, mesonic exchange currents, isobar configurations. For th e same reason, it is expected to be sensitive to relativistic effects. The impulse approximation contribution is considered here in the rela tivistic, explicitly covariant, light-front dynamics and compared to t he non-relativistic result. Only the S-1(0) final state, which largely dominates the cross section, is retained. It is found that relativist ic effects required by covariance compare to the uncertainty on NN wav e functions and are not as large as effects evidenced by similar studi es for the deuteron elastic form factors.
