Central Nucleus of a Confinement

Introduction In directional physics, a particle is not an elementary point but an internal structure composed of a directional confinement containing a set of vibrating strings. At the center of this confinement lies a fundamental element: the directional nucleus. This document presents the nature, function, and dynamics of the central nucleus of a confinement, as well as its behavior during nuclear reactions. It introduces a new interpretation of internal particle cohesion, directional polarity, and nuclear binding mechanisms.
