Researchers at CERN’s Large Hadron Collider (LHC) have, for the first time, directly observed high-energy electron and muon neutrino interactions in the teraelectronvolt (TeV) range using the Forward Search Experiment (FASER).

This groundbreaking achievement, described as a major breakthrough in particle physics, marks the first physics result on neutrinos from a particle collider.

The FASERν detector, a key component in the experiment, allowed scientists to identify neutrino interactions with high precision.

The study provided the first measurements of neutrino interaction cross-sections in the 560–1760 GeV range, filling a crucial gap in our understanding and aligning with Standard Model predictions, Interesting Engineering has reported.

These findings could offer insights into fundamental questions about particle mass and the matter-antimatter imbalance in the universe.

The research was published in Physical Review Letters on July 11, 2024.
