Illustration of the FASER experiment. Physicists are hopeful that FASER will capture new light particles that have previously evaded detection and could potentially help explain dark matter. Their elusiveness has been the source of much intrigue (and, of course, research funding) within the particle physics community since.What else makes them so curious? Neutrinos come in three flavors — electron neutrino, muon neutrino, and tau neutrino — and may switch between them through the process of oscillation. Initially proposed in 2018, the ForwArd Search ExpeRiment (FASER) is CERN’s newest experiment poised to detect neutrinos, potentially up to 1300 electron neutrinos, 20,000 muon neutrinos, and 20 tau neutrinos.
