In a first, neutrinos were caught interacting at the Large Hadron Collider

A proof-of-concept experiment paves the way for a larger detector in 2022

The FASER experiment (illustrated) will search for hard-to-spot particles at the Large Hadron Collider. That includes neutrinos, for which scientists will use the FASERν detector (yellow, in the trench at right). A pilot version of the detector just reported its first results.

The Large Hadron Collider’s claim to fame is its ability to unveil elusive subatomic particles.
