For a long time, we thought of Protons as fundamental particles, but eventually, we determined that they were not and that they were in fact made from particles called quarks and gluons. This dramatically changed how we viewed the fundamental building blocks of everything around us. Now many of us know that protons are made from two up quarks and one down quark that are bound together with gluons. But it turns out that this is a great oversimplification. Matter-antimatter particle pairs constantly form and annihilate all throughout the universe. We have known about this for a long time but what we didn’t understand is the extent to which it was occurring inside protons.
One startling result is that charm-anticharm pairs can sometimes be observed inside of protons. This is surprising because charm quarks are larger and heavier than protons. This is another major departure from the simple 3 quark model of the proton. In this video, I briefly talk about the history of growing our understanding of the proton and the more recent results.
