Abstract
Electromagnetic form factors of the deuteron are calculated within the relativistic approach based upon the clothed-particle representation for the field Hamiltonian of interacting mesons (\(\pi \), \(\eta \), \(\rho \), \(\omega \), \(\delta \), \(\sigma \)) and nucleons. The deuteron in the instant form of relativistic dynamics for such a system is the bound state of the clothed neutron and proton on their mass shells. This fact allows us to get rid of non-relativistic uncertainties inherent in the conventional approaches in the past. In particular, we do not need to “invent” any off-mass-shell models for the \(\gamma N\), \(\gamma \pi \), \(\gamma \rho \), etc. vertices. The S- and D- components of the deuteron wave function for the meson-exchange N-\(\pi \) interactions have been computed lately.
