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

The Large Hadron Collider s claim to fame is its ability to unveil elusive subatomic particles. But there s one class of particle that it had never directly detected, even though it produces them in abundance. Neutrinos, minute elementary particles, interact so little with matter that they sail through the particle accelerator s massive detectors unnoticed (SN: 4/8/21).

Now, in a proof-of-concept experiment, the first evidence for neutrino interactions at the LHC has been spotted, researchers with the FASER collaboration report May 13 at The technique could open up a window to neutrinos at energies for which the particles  interactions are poorly understood.

It s not a surprise to find neutrinos at the LHC.  This isn t the Earth-shattering result,  says particle physicist Deborah Harris of York University in Toronto and Fermilab in Batavia, Ill., who was not involved with the research.  Instead, it shows that detecting neutrinos at the LHC is possible.  This idea is not totally crazy,  she says.
