The standard model of particle physics has proven to be a robust machinery in describing processes involving the smallest components of our Universe. Despite its success, unanswered questions remain: What is the mechanism for neutrinos to acquire mass? Why is Charge-Parity symmetry highly conserved in QCD? What is the reason for the particle-antiparticle asymmetry in the Universe? And what is really dark matter?
Extremely sensitive detectors placed deep underground, such as dual-phase liquid xenon time projection chambers, can aid to answer these questions. In particular, the XLZD Observatory is a planned 80-tonne liquid xenon time projection chamber, with high sensitivity to a plethora of rare interactions of matter. Low background terrestrial experiments are complementary to searches in accelerators, in an exciting research field that spans particle, astro- and nuclear physics.
