Fig. 5: Projected sensitivity of HydroX.
From: HydroX, a light dark matter search with hydrogen-doped liquid xenon time projection chambers
The dark matter reach of a 500-day run of LZ doped with H2 under three different analysis assumptions discussed in the “WIMP Sensitivity" subsection of the “Results and discussion” is shown by the orange lines. a compares the sensitivity with SI projections from other existing and proposed experiments7,22,23,87,90,94,95, while b compares to other SD DM–proton interactions, where there are no other sensitive experiments at low DM masses; a recent NEWS-G result is just above the plot, and we also show the LZ SD-neutron sensitivity for comparison87,96,97,98,99. The sensitivity of HydroX per nucleon is the same for SI and SD-proton interactions, and extends well below 100 MeV in mass.
