Strange Quantum Experiment Shows Protons Have More ‘Charm’ Than We Thought

Protons may have more “charm” than we thought, according to new research.

A proton is one of the subatomic particles that make up the nucleus of an atom. As small as protons are, they are made up of even smaller particles elementary particles known as quarks, which come in a variety of “flavors” or types: high, low, strange, charm, low, and high. Typically, a proton is thought to be made up of two up quarks and one down quark.
