The price of natural flavour conservation in neutral weak interactions
The natural conservation of flavours in neutral weak interactions severely constrains choices of gauge groups and their fermion representations. In the absence of exactly conserved quantum numbers other than charge, and of mod Delta Q mod >or=2 charged currents, essentially the only weak and elec...

| description | The natural conservation of flavours in neutral weak interactions severely constrains choices of gauge groups and their fermion representations. In the absence of exactly conserved quantum numbers other than charge, and of mod Delta Q mod >or=2 charged currents, essentially the only weak and electromagnetic gauge groups whose neutral interactions naturally conserve all flavours are SU(2)/sub L /(X)U(1) and SU(2)/sub L/(X)(U(1))/sup 2/. The plausible extensions of these gauge groups to grand unified models including the strong interactions are based on SU(5) and SO(10) respectively. Properties of SU(5) and SO(10) models are discussed. (24 refs). |
