If you have a question about this talk, please contact Marco Nardecchia. The existence of dark matter is one of the few solid hints for physics beyond the standard model. If dark matter indeed has particle nature, then direct detection via scattering on atomic nuclei is one of the most promising discovery channels. Effective field theories are the appropriate framework to describe the scattering process that involves physics at very different energy scales. The state of the art is to include also subleading (for instance, velocity-suppressed or spin-dependent) interactions, either in an attempt to resolve tensions between different experimental results, or to accommodate concrete models of dark matter. Here, electroweak corrections can have a large impact on the interpretation of data, via the mixing of suppressed into unsuppressed operators. In this talk I report on our effort to provide a complete framework of effective theories, connecting all relevant energy scales from the UV down to the nuclear scale. We also calculate the electroweak operator mixing for dark matter furnishing a general representation of the electroweak gauge group, and I will show preliminary results of our analysis.
