The baryon number conservation law and the three lepton number conversation law are valid for all physical processes. However, conservation of strangeness is valid only for strong nuclear interactions and electromagnetic interactions.

In the process the nucleus emits a beta particle (either an electron or a positron) and quasi-massless particle, the neutrino.
