The Colored Plum Pancake Model:The Composite Proton and Neutron Molecules

We present a new model in which protons and neutrons are treated as composite “molecules” of sub-constituents, combining geometrical insights from J.J. Thomson´s early corpuscular atom with modern framework of quantum chromodynamics (QCD). Inspired on one side by Thomson´s extended distributions of charge and his mechanically stable electron configurations, and on the other by quark-gluon description of hadrons in QCD, we construct a hybrid picture where nucleons are structured objects built from clustered, interacting color charges. This “composite nucleon molecule” model aims to provide an intuitively accessible, quasi-classical representation of the internal proton and neutron structures that remain compatible with key constraints on form factors, plum distributions, and spin observables. We outline the basic architecture of the model and highlight several novel qualitative properties and testable consequences for low-energy nucleon observables. E.g., the neutron decay and the deuteron-triton fusion are described using this colored plum pancake model.
