‘Ghostly’ neutrinos provide new path to study protons

Posted by in category: particle physics

Neutrinos are one of the most abundant particles in our universe, but they are notoriously difficult to detect and study: they don’t have an electrical charge and have nearly no mass. They are often referred to as “ghost particles” because they rarely interact with atoms.

But because they are so abundant, they play a large role in helping scientists answer fundamental questions about the universe.

In groundbreaking research described in Nature —led by researchers from the University of Rochester—scientists from the international collaboration MINERvA have, for the first time, used a beam of neutrinos at the Fermi National Accelerator Laboratory, or Fermilab, to investigate the structure of protons.
