Scientists achieved the groundbreaking detection of neutrinos generated within a particle collider, marking the first direct observation of collider-produced neutrinos. These elusive subatomic particles, known as “ghost particles,” typically traverse matter without interacting due to their negligible mass and lack of electric charge. The discovery was made possible using the FASERnu detector at the Large Hadron Collider (LHC). The detection, now officially documented in two peer-reviewed papers, offers insights into neutrino formation, properties, and their role in the universe’s evolution. Neutrinos, highly abundant yet elusive, are crucial for unraveling mysteries of particle astrophysics, expanding the LHC’s scientific potential.
