Breakthrough Experiment Reveals Neutron’s Internal Structure

Share

A long experiment finally showed us the inside of particles called neutrons, helping us understand more about the smallest parts of matter. The data from the Central Neutron Detector at TJNAF is helping us learn more about how neutrons work. Neutrons are made up of even smaller particles called quarks and gluons. Quarks and gluons are always moving and changing in a chaotic way.

Physicists shoot tiny bullets at particles to see how they move. This helps us understand partons, which are units of quarks and gluons. We have learned a lot about protons, but neutrons are still a mystery. A new detector at TJNAF is helping us gather more information about neutrons. We are studying how quarks in neutrons are different from quarks in protons.

Understanding the insides of atoms will give us new knowledge about quantum mechanics. This research is in a journal called Physical Review Letters.
