I’ve recently read that the strong interaction, that holds the quarks together to form protons and neutrons, also creates a residual force called the nuclear force, which holds the neutrons and protons together. Why and how is the nuclear force a consequence of the strong interaction?

1$\begingroup$ The answer is the Yukawa meson theory of nuclear force. It involves the exchange of pions between the nucleons, which binds them together. $\endgroup$– user137661Jun 12, 2019 at 23:06

2$\begingroup$ A residual force is a more general concept. For example, the force that binds electrically neutral atoms together to form molecules is also a residual force. There's no big mystery about it. The force is zero to first order, but it exists in higher orders of approximation. $\endgroup$– user4552Jun 13, 2019 at 1:40

The nuclear force arises from the strong interaction and virtual gluon exchanges and color fluctuations within the quarks of the nuclei creat pions that are exchanged between nucleons

2$\begingroup$ The beginning of your statement is essentially the definition of the strong force. Could you go more in depth about the creation and exchange of pions? $\endgroup$– user195162Jun 13, 2019 at 1:48
