SU(3) Charged and hypercharged coheremt state and the color quantum number

We extend the coherent state which possesses definite Abel charge to the state possessing definite non-Abel charge, and construct SU(3) charged and hypercharged coherent states for both boson and fermion. In this way, the fractionally charged and hypercharged quark states can be obtained naturally. Moreover, this formulation also shows that in order to obtain integrally charged and hypercharged hadroh coherent state, one must introduce color quantum number and discuss the SU (6)⊕SU_c(3) case.
