Question

Quizplus · Accepted Answer

Baryons, which include protons and neutrons among others, are a type of composite subatomic particle made up of three quarks. A fundamental property of baryons is that they have half-integer spin, making them fermions according to the spin-statistics theorem. This means they follow Fermi-Dirac statistics and obey the Pauli exclusion principle. The spin of baryons is not 0 but can be $+\frac{1}{2}$ or $-\frac{1}{2}$ (and in some cases higher, depending on the composition), which is what is meant by half-spin.
