Impact of nuclear structure from shell model calculations on nuclear responses to WIMP elastic scattering for ${}^{19}$F and ${}^{nat}$Xe targets

Abstract

Non-relativistic effective field theory (NREFT) is one approach used for describing the interaction of WIMPs with ordinary matter. Among other factors, these interactions are expected to be affected by the structure of the atomic nuclei in the target. The sensitivity of the nuclear response components of the WIMP-nucleus scattering amplitude is investigated using shell model calculations for ${}^{19}$F and ${}^{nat}$Xe. Resulting integrated nuclear response values are shown to be sensitive to some specifics of the nuclear structure calculations.
