Neutron has a baryon number of 1 and so it is conserved in your example. Even in normal matter, some elements undergo Electron Capture (p + e- -> n + ν). But baryon number conservation is an asserted symmetry and there is no fundamental reason it holds. Finding proton decay would demonstrate that it does not but so far there is no evidence that protons (or bound neutrons) spontaneously decay. |
