WebThe theory of nucleon decay can be distinguished by the mechanism by which the baryon number of the nucleon is reduced to zero in the final state products. Two general possibilities have been proposed, which we can indicate schematically: 1. Nucleon → 3 quarks → antilepton + antiquark + quark 2. Webnucleon: [noun] a proton or neutron especially in the atomic nucleus.
