Query: Investigation on light dark matter   Some extensions of the Standard Model provide Dark Matter candidate particles
with sub-GeV mass. These Light Dark Matter particles have been considered for
example in Warm Dark Matter scenarios (e.g. the keV scale sterile neutrino,
axino or gravitino). Moreover MeV scale DM candidates have been proposed in
supersymmetric models and as source of the 511 keV line from the Galactic
center. In this paper the possibility of direct detection of a Light Dark
Matter candidate is investigated considering the inelastic scattering processes
on the electron or on the nucleus targets. Some theoretical arguments are
developed and related phenomenological aspects are discussed. Allowed volumes
and regions for the characteristic phenomenological parameters of the
considered scenarios are derived from the DAMA/NaI annual modulation data.
