CERN collider detects neutrino for the first time - Inverse

Millions of barely perceptible “ghost” particles called neutrinos fly through our bodies at every second.

These magnetic traffic signs don’t impact chargeless particles like neutrinos.

Like FASER, these experiments all focus on detecting the constituent parts of a neutrino that it decays into after striking an atomic nucleus just right.

But regardless of size, FASER works the same way using technology reminiscent of film photography called emulsion detection to catch neutrinos:.

Before the FASER experiment, only 10 tau neutrinos had ever been observed, with the first detection occurring only twenty-one years ago at Fermilab.

In addition to differentiating between different flavors of neutrinos, FASER will also be able to distinguish between neutrinos and anti-neutrinos striking its detector.

However, because both neutrinos and anti-neutrinos are electromagnetically chargeless, this opposite charge refers to the particles’ lepton number instead — a kind of quantum number used to describe the properties of subatomic particles.

However, studying more anti-neutrinos directly using experiments like FASER will be a big step toward answering this question.
