![]() Useful for parametrizing direct detection signals, the effect of such continuum Non-relativistic effective theory of dark matter-baryon scattering, which is This could arise, for instance, from coupling to a sector which isĪpproximately conformal at the relevant momentum transfer scale. ![]() Study an alternative, in which a continuum of light mediator states may beĮxchanged. Simple contact interaction or as the exchange of a light mediator particle. Many models of dark matter scattering with baryons may be treated either as a (For interpretation of the references to color in this figure legend, the reader is referred to the web version of this article.) No DM signal below Er=3 keV is included due to limitations of the measured Leff, in accordance with the collaboration's analysis. The 14% S1 light gathering efficiency is included but selection cuts are not. Bottom: S1 spectra at LUX (mN=131 GeV) with 10065.4 kg⋅days exposure for dmDM (solid) and WIMP DM (dotted) of mass 10 (red), 20 (blue) and 50 (green) GeV. Experimental efficiencies are not included, and the recoil spectrum is shown only for Er>3 keV because the dmDM spectrum is so sharply peaked at the origin that no other features would be visible if it were included. Top: Nuclear recoil spectra at CDMS II Silicon (mN=28 GeV) with 140.2 kg⋅days exposure for dmDM (solid) and WIMP DM (dotted) of mass 5 (red), 10 (blue) and 50 (green) GeV.
