Quantum number conservation in meson interactions

Quantum number descriptions of spin-zero mesons are obtained from their quark/anti-quark structures, extending the application of the already established seven quantum number conservation in fermion interactions to include mesons. This provides a new tool in the design of experiments and the analysis of results, making it particularly useful for those interactions that involve neutral mesons. One quantum number is parity, conflicting with the evidence for parity non-conservation. The origin of this disagreement is identified as the poor definition of parity in the Standard Model. It is shown that neutral mesons can produce inter-generational interactions, providing an alternative to the see-saw mechanism.
