The search for the sterile neutrino

Back when it was theorized, scientists weren’t sure they would ever detect the neutrino; now they’re searching for a version of the particle that could be even more elusive.

Which neutrino is the heaviest?

The question may seem simple, but physicists don’t yet know the answer. New measurements aim to change that.

The LBNF beamline will use a one-megawatt capable focusing horn to direct the charged particles that become neutrinos.
