The strong force binds quarks in protons from "summary" of The Quantum Universe by Brian Cox,Jeff Forshaw
The strong force is the glue that holds the fundamental building blocks of matter, called quarks, together inside protons. Without this force, the quarks would fly apart due to their mutual repulsion. The strong force is one of the four fundamental forces in nature, along with gravity, electromagnetism, and the weak force. It is the strongest of these forces but also has the shortest range, acting only over distances comparable to the size of an atomic nucleus. Quarks are never found in isolation but are always bound together in groups of two or three by the strong force. These groups of quarks form particles known as hadrons, which include protons and neutrons. Inside a proton, for example, there are three quarks bound together by the strong force. The strong force is mediated by particles called gluons, which carry the force between quarks. Gluons are unique in that they themselves carry the strong force, unlike photons that mediate the electromagnetic force. This self-interaction of gluons leads to a phenomenon known as confinement, where quarks are always confined within particles like protons and cannot exist in isolation. As quarks move farther apart, the strong force between them increases, making it more energetically favorable for a new quark-antiquark pair to be created out of the vacuum to form new particles. The strong force is responsible for the stability of protons and neutrons within atomic nuclei. Without this force, the positively charged protons would repel each other, causing the nucleus to disintegrate. The strong force overcomes the electromagnetic repulsion between protons and binds them together in the nucleus. This binding energy is what holds the nucleus together and is crucial for the stability of matter as we know it. In summary, the strong force is a fundamental force that binds quarks together inside protons and other hadrons. It is carried by gluons and is responsible for the stability of atomic nuclei. Without the strong force, quarks would not be confined within particles, leading to the breakdown of matter as we know it.
