 Spin-statistics theorem

The Spin-Statistics Theorem is a fundamental principle in quantum field theory that governs the relationship between the intrinsic spin of particles and the type of statistics they obey. It provides a foundational explanation for why particles with integer spins (such as photons and W/Z bosons) are described by Bose-Einstein statistics, while particles with half-integer spins (such as electrons and quarks) are described by Fermi-Dirac statistics.
