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…
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…
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…
