Summary
A statistical model utilizing the Thomas-Fermi approximation is advanced which, by assuming Z0 and W± bosons to be massless particles like photons, explains the short range of weak forces by means of the screening properties of the negative-kinetic-energy neutrino distribution which, according to the Dirac equation, fills the whole universe. In addition, a conjecture is proposed ascribing the current electron and neutrino masses to an evolutive process which took place while the universe was cooling.
