Effective Theory and the Nuclear Physics of Dark Matter Detection

摘要

I discuss a recently developed Galilean-invariant effective theory of dark-matter/nucleon interactions, the embedding of this interaction in nuclei, and the calculation of the resulting response functions for a variety of nuclear targets. The construction, based on symmetry principles, yields six independent response functions contributing to dark matter/nucleus elastic scattering, in contrast to conventional descriptions that include only spin-independent and spin-dependent scattering.
