Spin is an intrinsic form of angular momentum possessed by subatomic particles
Subatomic particles possess an intrinsic form of angular momentum known as spin, which is firmly established within quantum mechanics and modern physical theory.
The claim is a well-established foundational tenet of quantum mechanics and particle physics. The retrieved papers consistently treat spin as intrinsic angular momentum of subatomic particles or discuss its foundational geometric and canonical definitions, supporting the claim without any credible refutation of the core concept.
