Information divergences to parametrize astrophysical uncertainties in dark matter direct detection
Gonzalo Herrera, Andreas Rappelt
Astrophysical uncertainties in dark matter direct detection experiments are typically addressed by parametrizing the velocity distribution in terms of a few uncertain parameters th…
Conservative constraints on the effective theory of dark matter-nucleon interactions from IceCube: the impact of operator interference
Anja Brenner, Alejandro Ibarra, Andreas Rappelt
We present a method to derive conservative upper limits on the coupling constants of the effective theory of dark matter-nucleon interactions, taking into account the interference…
New Constraints on Supersymmetry Using Neutrino Telescopes
Stephan Meighen-Berger, Matteo Agostini, Alejandro Ibarra +5
We demonstrate that megaton-mass neutrino telescopes are able to observe the signal from long-lived particles beyond the Standard Model, in particular the stau, the supersymmetric…
Impact of substructure on local dark matter searches
Alejandro Ibarra, Bradley J. Kavanagh, Andreas Rappelt
Dark matter substructure can contribute significantly to local dark matter searches and may provide a large uncertainty in the interpretation of those experiments. For direct detec…
Bracketing the impact of astrophysical uncertainties on local dark matter searches
Alejandro Ibarra, Bradley J. Kavanagh, Andreas Rappelt
The theoretical interpretation of dark matter (DM) experiments is hindered by uncertainties on the dark matter density and velocity distribution inside the Solar System. In order t…
