We explore the dark matter interpretation of the anomalies claimed by the
DAMA and CoGeNT experiments, in conjunction with the various null
direct-detection experiments. An independent analysis of the CoGeNT data is
employed and several experimental and astrophysical uncertainties are
considered. Various phenomenological models are studied, including isospin
violating interactions, momentum-dependent form factors, velocity-dependent
form factors, inelastic scatterings (endothermic and exothermic) and
channeling. We find that the severe tension between the anomalies and the null
results can be ameliorated but not eliminated, unless extreme assumptions are
made.
