Description
Understanding the fundamental properties of neutrinos and the nature of dark matter are two major challenges in modern physics. Both require detecting events that, if they exist, are extremely rare and easily hidden by background signals. In this talk, I will give an overview of current strategies to search for such rare events and explain the experimental challenges shared by both fields. I will begin with the scientific motivations for these searches and then show why reducing background is essential to make any detection possible. I will then present examples of detector technologies, especially scintillators and cryogenic bolometers. I will present the TESSERACT experiment, a future dark-matter search to which the French community contributes through the development of new cryogenic detectors with the TES4DM project, to be installed at the Modane Underground Laboratory (LSM), with first science data expected in 2028.
