Unlike the traditional view, in which these particles are regarded as almost inert byproducts of weak interactions, the Neutrino Model proposes that neutrinos act as protective shields for opposite charges inside atomic nuclei, preventing the annihilation of latent electrons and positrons . According to this model, beta decays, electron capture, and heavy lepton decays (muons and taus) are not destructive events but internal reorganizations mediated by neutrino protection . The model also predicts the existence of transient neutral states (¦Ì?, ¦Ó?) absorbed by nuclear matter, offering a possible explanation for latent nuclear stability and the cosmic balance between matter and antimatter . It also interprets the possible destruction of matter, but always based on electron¨Cpositron annihilation. Although still hypothetical, the Neutrino Model provides a new perspective on matter¨Cantimatter coexistence, suggesting that the balance between opposing forces is embedded in nuclear structure. This approach proposes experimentally testable hypotheses and opens pathways to new interpretations in nuclear physics and cosmology . https://pubs.sciepub.com/ijp/13/5/1/ijp-13-5-1.pdf Neutrino antineutrino beta decay positron electron proton neutron antimatter nuclear stability leptonic reorganization nuclear reorganization matter¨Cantimatter coexistence
