| 19:00 - 20:00 Weekly Seminar HEPCo Group Daily modulation of low-energy nuclear recoils from sub-GeV dark matter School PHYSICS Date and time Tuesday, April 8th, 2025 (Farvardin 19th, 1404), 7:00 pm (Tehran zone) Link https://www.skyroom.online/ch/schoolofphysics/highenergyseminar Abstract At sufficiently low nuclear recoil energy, the scattering of dark matter (DM) in crystals gives rise to single phonon and multiphonon excitations. In anisotropic crystals, the scattering rate into phonons modulates over each sidereal day as the crystal rotates with respect to the DM wind. This gives a potential avenue for directional detection of DM. The daily modulation for single phonons has previously been calculated. He ... |
