GeV WIMPs scattering off of OH impurities cannot explain the DAMA signal
  In the presence of OH impurities in the DAMA crystals, GeV-scale WIMPs
elastically scattering off of hydrogen nuclei with a spin independent cross
section of $\sim 10^{-33}\ {\rm cm}^2$ might explain the annual modulation
observed by the DAMA experiment, while being consistent with other direct dark
matter searches, as scattering would occur at energies below the energy
threshold of other detectors. In this work we examine this possibility and show
that, independent of the level of OH impurities in the DAMA crystals, for
several reasons this scenario does not provide a viable explanation to the DAMA
signal.
