Аннотация: Abstract—We present new calculation results for the NEWSdm emulsion detector response to dark matter(DM) particles accelerated in elastic interactions with cosmic-ray nuclei (Cosmic-Ray-accelerated DarkMatter or CRDM) for different thresholds. The NEWSdm detector, located in the Gran Sasso laboratory(INFN, Italy), consists of 10 kg of NIT (Nano Imaging Tracker) emulsion films with grain sizes of severaltens of nanometers. It has been shown that for such a mass of nano-emulsion, in the DM mass rangefrom 1 keV/c2 to 1 GeV/c2 with cross-section values σχp ranging from 10−30 to 10−28 cm2 , it is possibleto obtain new constraints on DM properties. Using the micrOM EGAs code, the parameter space of thelight dark matter model (Z portal) was determined which does not contradict the cosmological constraintsand leads to the considered interaction cross sections σχp .
