The structure of hadronic flavours and weak interactions as deduced from quantum gravity and its GUT extension

In QG and its GUT extension, the valence parts of quarks are called ''quanta''. It is argued why flavoured quanta should be multiple-quanta structures entirely made of ordinary up- and down-quanta. In fact, corresponding 3-quanta structures are presented to satisfy all we need. The existence and structure of additional quark generations is predicted. It is shown that, after resolving all flavours into these 3-quanta structures based on QG, weak interactions of all kind are conserving all their quantum numbers absolutely. ''Broken'' quantum numbers do not exist. This is exemplified by analyzing various weak decay modes of baryons, mesons, and the weak bosons. Thus, not only the ordinary beta-decay of baryons, mesons, and the weak bosons is scrutinized, but also purely non-leptonic and mixed modes. All this is based on the fundamental indivisibility of a particle into a valence and a separate non-valence part in QG, denied by quantum field theories.
