abstract
We perform nuclear shell model calculations of the neutralino-nucleus cross section for several nuclei in the A = 127 region. Each of the four nuclei considered is a primary target in a direct dark matter detection experiment. The calculations are valid for all relevant values of the momentum transfer. Our calculations are performed in the $3s 2d 1g_{7/2} 1h_{11/2}$ model space using extremely large bases, allowing us to include all relevant correlations. We also study the dependence of the nuclear response upon the assumed nuclear Hamiltonian and find it to be small. We find good agreement with the observed magnetic moment as well as other obervables for the four nuclei considered: ^{127}I, ^{129,131}Xe, and ^{125}Te.

Simulations of 3-Dimensional Recoil Response to Coherent Elastic Neutrino-Nucleus Scattering Events in Directional Direct Dark Matter Detectors
Simulations of solar CEvNS events produce annually varying ring-like 3D recoil distributions in directional detectors that lack target dependence and contrast with fixed WIMP signals.
