| Physicists have long known that types of quarks and antiquarks combine in twos and threes to form more-complex particles such as protons and neutrons. Particles called baryons, such as protons and neutrons, contain three quarks or antiquarks each. Until recently, quarks and antiquarks were observed only in groups of twos or threes. |
