Halo-independent tests of dark matter direct detection signals

Abstract [en]

We discuss a new halo-independent framework that can be used to relate dark matter direct detection signals with constraints from LHC, indirect detection and the thermal freeze-out paradigm. From an observed direct detection signal we show that a lower bound on the product of the dark matter-nucleon cross section and the energy density, that is independent of the velocity distribution, can be derived. This allows to obtain strong and robust halo-independent constraints on particle physics models. We also extend this framework to the case of annual modulation signals and we illustrate the use of the lower bounds with the DAMA signal. © Copyright owned by the author(s) under the terms of the Creative Commons Attribution-NonCommercial-NoDerivatives 4.0 International License (CC BY-NC-ND 4.0).
