Mass spectrum of diquarks and mesons in the color--flavor locked phase of dense quark matter

The spectrum of meson and diquark excitations of dense quark matter is considered in the framework of the Nambu -- Jona-Lasinio model with three types of massless quarks in the presense of a quark number chemical potential \(\mu\). We investigate the effective action of meson- and diquark fields both at sufficiently large values of \(\mu>\mu_c\approx 330\) MeV, where the color--flavor locked (CFL) phase is realized, and in the chirally broken phase of quark matter (\(\mu\mu_c\).
