  It is known that some of the deeply-virtual-Compton-scattering observables,
for instance, the beam-charge asymmetry in the hard electroproduction of real
photons on the nucleon, are extremely sensitive to the magnitude of D-term
appearing in the parameterization of the generalized parton distributions. We
report a theoretical analysis of both the isoscalar and isovector parts of the
nucleon D-term within the framework of the chiral quark soliton model, without
recourse to the derivative expansion type approximation used in previous works.
