Can Light-nuclei Search Experiments Constrain the Spin-independent Dark Matter Phase Space?

At present, restrictions on the spin-independent parameter space of WIMP dark matter searches have been limited to the results provided by relatively heavy nuclei experiments, based on the conventional wisdom that only such experiments can provide significant spin-independent limits. We examine this wisdom, showing that light nuclei experiments can in fact provide comparable limits given comparable exposures, and indicating the potential of light nuclei detectors to simultaneously and competitively contribute to the search for both spin-independent and -dependent WIMP dark matter.
