These neutrinos obtained at the Large Hadron Collider (LHC) have properties completely consistent with the Standard Model, allowing scientists to study these elusive particles more comprehensively and test fundamental physical theories.

Although low-energy neutrinos such as solar neutrinos and ultra-high-energy neutrinos from deep space have been detected before, high-energy neutrinos in the range of 200-300 GeV to 10 TeV It has never been artificially created on Earth..

Details of the experiment

The FASER® detector used in the experiment has a total weight of 1.1 tons and consists of alternating tungsten plates and photoemulsion. Focusing on the detector’s volume, which is equivalent to about 129 kilograms, the researchers identified four candidate events from the interaction of electron neutrinos and eight candidate events from the interaction of muon neutrinos.

All identified events had a confidence level above 5 “sigma”, which is equivalent to a scientific discovery. Candidates for neutrino production were found in the energy range of 520 to 1760 GeV, a relatively unexplored range.

This discovery is further evidence that the Standard Model accurately describes the properties of neutrinos and deepens our understanding of these particles. The successful production and detection of high-energy neutrinos in a controlled environment opens new ways to test theories in fundamental physics and expands the boundaries of scientific knowledge.
