Zusammenfassung: | JCAP 03 (2024) 047 Direct detection experiments and the interpretation of their results are
sensitive to the velocity structure of the dark matter in our galactic halo. In
this work, we extend the formalism that deals with such astrophysics-driven
uncertainties, originally introduced in the context of dark-matter-nuclear
scattering, to include dark-matter-electron scattering interactions. Using mock
data, we demonstrate that the ability to determine the correct dark matter mass
and velocity distribution is depleted for recoil spectra which only populate a
few low-lying bins, such as models involving a light mediator. We also
demonstrate how this formalism allows one to test the compatibility of existing
experimental data sets (e.g. SENSEI and EDELWEISS), as well as make predictions
for possible future experiments (e.g. GaAs-based detectors). |
