The electromagnetic form factors of the deuteron, particularly the quadrupole form factor, are studied with a help of a phenomenological Lagrangian approach where the vertex of the deuteronproton-neutron with D-state contribution is explicitly taken into account. The result shows the importance of this contribution to the quadrupole form factor in the approach.

The generalized parton distribution functions of a deuteron are studied based on a phenomenological effective Lagrangian approach. The obtained deuteron generalized parton distribution functions are expressed explicitly in terms of the ones of the nucleon.

A phenomenological Lagrangian approach is employed to study the electromagnetic properties of deuteron. The deuteron is regarded as a loosely bound state of a proton and a neutron. The deuteron electromagnetic form factors are expressed in light-front representation in the transverse plane. The transverse charge density of the deuteron is discussed.

The generalized parton distribution functions of deuteron are studied based on a phenomenological effective Lagrangian approach. The electric, magnetic and quadrupole form factors are estimated. Moreover, the tensor structure function of the deuteron is discussed.
