Strange Charm: A Song about Quarks

Gluons bind quarks into particles like protons or neutrons. Here, three quarks — two ups and a down — are depicted forming a proton, held together by the exchange of (invisible) gluons. Because gluons carry color charge they can interact with one another to form glueballs, which decay into particles made of quarks and antiquarks. (Illustration courtesy Jefferson Lab
