There is recently some interest in light dark matter, Mdm ~
GeV. This interest is motivated by direct detection experiment
anomalies, most notably DAMA and CoGeNT (and to some extent CDMS-II). I
will first review the experimental situation. Then I will argue that the
data, together with the cosmological observations of the relic abundance
of dark matter, point to a very simple candidate, a singlet scalar
particle, interacting with the visible sector (ie the Standard Model)
through the Higgs field. I will conclude with a discussion on the
potential implications of this model for indirect searches of dark
matter as well as the search of the Higgs at the LHC.
