In fact, a look at the structure of SU(2)⊗U(1)Y tells us that both, the electric charge generator Q and its corresponding electromagnetic gauge field Aμ(x),are not basic constituents of this gauge group. %K Matemática Aplicada %K Grupos isomórficos %K Indicadores de grupos %K Interacciones electromagnéticas %K Restricciones globales %~ GOEDOC, SUB GOETTINGEN
