“…In the left plot, we assume no scaling with A; in the right plot, we assume the cross section scales like A 4 (e.g., with two powers coming from nuclear coherence, and two from kinematic factors). Limits are shown from DEAP-3600 [79], DAMA [80,81], interstellar gas clouds [82,83], a recast of CRESST and CDMS-I [84], a recast of CDMS and EDELWEISS [85,86], a detector in U. Chicago [87], a XENON1T single-scatter analysis [88], tracks in the Skylab and Ohya plastic etch detectors [81], in ancient mica [89], the MAJORANA demonstrator [88], IceCube with 22 strings [90], XQC [91], CMB measurements [92,93], and IMP [94]. Also shown is the future reach of the liquid scintillator detector SNO+ as estimated in [95,96].…”
