DESCRIPTION:The existence of dark matter is one of the few solid hints for
  physics beyond the standard model. If dark matter indeed has particle nat
 ure\, then direct detection via scattering on atomic nuclei is one of the 
 most promising discovery channels. Effective field theories are the approp
 riate framework to describe the scattering process that involves physics a
 t very different energy scales.\n\nThe state of the art is to include also
  subleading (for instance\, velocity-suppressed or spin-dependent) interac
 tions\, either in an attempt to resolve tensions between different experim
 ental results\, or to accommodate concrete models of dark matter. Here\, e
 lectroweak corrections can have a large impact on the interpretation of da
 ta\, via the mixing of suppressed into unsuppressed operators.\n\nIn this 
 talk I report on our effort to provide a complete framework of effective t
 heories\, connecting all relevant energy scales from the UV down to the nu
 clear scale. We also calculate the electroweak operator mixing for dark ma
 tter furnishing a general representation of the electroweak gauge group\, 
 and I will show preliminary results of our analysis.
