Anisotropic electron scattering and Migdal effect in semiconductor detectors
Aula Al-Adulrazzaq, Paolo Settembri, Sebastian Sassi +4
Cryogenic semiconductor detectors are widely used in dark matter direct detection. Electronic excitations in these materials can be caused either by direct dark matter electron sca…
Fast numerical evaluation of dark matter direct detection event rates
Sebastian Sassi, Aula Al-Adulrazzaq, Matti Heikinheimo +1
The mathematical expression for the dark matter nuclear recoil event rate in a detector consists of a six dimensional integral over the velocity distribution of dark matter in the…
Probing the dark matter velocity distribution via daily modulation
Matti Heikinheimo, Kai Nordlund, Sebastian Sassi +1
We consider dark matter velocity distributions with an anisotropic component, and analyze how the velocity structure can be probed in a solid state ionization detector with no dire…
Daily and annual modulation rate of low mass dark matter in silicon detectors
Abolfazl Dinmohammadi, Matti Heikinheimo, Nader Mirabolfathi +4
Low threshold detectors with single-electron excitation sensitivity to nuclear recoil events in solid-state detectors are also sensitive to the crystalline structure of the target…
Anisotropic ionization threshold and directional sensitivity in solid state DM detectors
Matti Heikinheimo, Sebastian Sassi, Kimmo Tuominen +2
The threshold displacement energy for nuclear recoils depends strongly on the direction of the recoiling nucleus with respect to the crystal lattice. Assuming that similar dependen…
Energy loss due to defect creation in solid state detectors
Matti Heikinheimo, Sebastian Sassi, Kimmo Tuominen +2
The threshold displacement energy in solid state detector materials varies from several eV to ~100 eV. If a stable or long lived defect is created as a result of a nuclear recoil e…
Energy loss in low energy nuclear recoils in dark matter detector materials
Sebastian Sassi, Matti Heikinheimo, Kimmo Tuominen +4
Recent progress in phonon-mediated detectors with eV-scale nuclear recoil energy sensitivity requires an understanding of the effect of the crystalline defects on the energy spectr…
Identification of the low energy excess in dark matter searches with crystal defects
Matti Heikinheimo, Sebastian Sassi, Kai Nordlund +2
An excess of events of unknown origin at low energies below 1 keV has been observed in multiple low-threshold dark matter detectors. Depending on the target material, nuclear recoi…
Solar neutrinos and dark matter detection with diurnal modulation
Sebastian Sassi, Abolfazl Dinmohammadi, Matti Heikinheimo +4
We investigate the diurnal modulation of the event rate for dark matter scattering on solid targets arising from the directionally dependent defect creation threshold energy. In pa…
