Sub-MeV dark matter detection with superfluid He-4: an effective theory approach
Angelo Esposito (EPFL)
--------------------------------------------------------------------------
Abstract: I will discuss the possibility of looking for sub-MeV dark matter using superfluid helium-4, which is currently the most promising proposal for such a mass range. In particular, I will employ the recently developed EFT for the superfluid phonon to describe the response of the detector to the passing dark matter. Being formulated in a quantum field theory language, this approach is particularly suitable for a particle physics problem like the one at hand, and presents several advantages with respect to the standard techniques. I will apply the formalism to a model of dark matter with both a scalar and vector mediator, and discuss the prospects for a future experiment.
