Abstract: The spectrum of meson and diquark excitations of the color-flavor lockedCFL phase of dense quark matter is considered in the framework of the Nambu- Jona-Lasinio model. We have found that in this phase all Nambu-Goldstonebosons are realized as scalar and pseudoscalar diquarks. Other diquarkexcitations are resonances with mass value around 230 MeV. Mesons are stableparticles in the CFL phase. Their masses vs chemical potential lie in theinterval 300$\div$500 MeV.
