Natura Simplex : Frontier Physics I

The proton spin, equal to 1/2, is an experimentally established property. However, its origin and the distribution of its contributions among the different internal degrees of freedom remain open questions. Within the framework of quantum chromodynamics, this distribution involves the intrinsic spins and orbital angular momenta of quarks and gluons. We propose an alternative perspective based on the Natura Simplex program. Within this framework, the proton is considered a coherent organization of phase, composed of three non-autonomous fragments corresponding to the UUD configuration. Its spin is then viewed as a global geometric property of this organization. This approach leads us to reconsider how the proton spin problem is formulated, emphasizing the geometric coherence of the whole rather than the addition of contributions from constituents considered separately.
