Scientists have achieved a major scientific breakthrough by successfully detecting neutrinos created in a particle collider for the first time. This groundbreaking development was made possible through the use of the FASERnu detector at the Large Hadron Collider (LHC) and the results were recently presented at a conference in Italy in March 2023. Neutrinos are subatomic particles that have very minimal interactions with other matter, making them incredibly difficult to study. However, they play a crucial role in high-energy situations such as nuclear fusion in stars and supernova explosions.
The FASERnu detector, consisting of tungsten plates interspersed with emulsion film layers, allows the collision of neutrinos with nuclei in the plates, resulting in detectable particle tracks. The detection and subsequent analysis of neutrinos produced in particle colliders provide valuable insights into the depths of space that cannot be obtained through alternate means. By gaining an understanding of how neutrinos are formed, their properties, and their impact on the evolution of the universe, scientists can unlock the full potential of the collider in terms of physics research.
The results obtained from the FASERnu detector are highly significant, with six neutrino candidates being identified in 2021. The recent publication further affirms this discovery, and ongoing data analysis is underway as the LHC enters its third run, scheduled to continue until 2026. This successful observation of neutrinos in particle colliders opens up new avenues for scientific research and exploration.
