According to the spin statistics theorem, what type of spin do fermions possess?

Fermions possess half-integer spin, which is a defining characteristic of these particles. According to the spin statistics theorem, particles with half-integer spin (like 1/2, 3/2, etc.) adhere to the Pauli exclusion principle. This principle states that no two fermions can occupy the same quantum state simultaneously. As a result, fermions include particles such as electrons, protons, and neutrons, which make up the matter in the universe.

In contrast, particles with integer spin, such as bosons, do not follow the exclusion principle; instead, they can occupy the same state, leading to different statistical behaviors. The distinction between fermions and bosons based on their spin type is essential for understanding various physical phenomena, including the behavior of solids, the properties of gases at low temperatures, and the fundamental workings of quantum field theory.
