Exchange force overlap, Pauli repulsion takes place. The same is true for protons and neutrons where due to their larger mass, the rigidity of baryons is much larger than that of electrons. Exchange force In physics the term exchange force has been used to describe two distinct concepts which should not be confused. The preferred meaning of exchange force is in particle physics, where it denotes a force produced by the exchange of force carrier particles, such as the electromagnetic force produced by the exchange of photons between electrons and the strong force produced by the exchange of gluons between quarks. The
Preon of these have gained wide acceptance in the physics world. However, in a recent work de Souza has shown that his model describes well all weak decays of hadrons according to selection rules dictated by a quantum number derived from his compositeness model. In his model leptons are elementary particles and each quark is composed of two "primons", and thus, all quarks are described by four "primons". Therefore, there is no need for the Standard Model Higgs boson and each quark mass is derived from the interaction between each pair of "primons" by means of three Higgs-like bosons. In his
