N2 - We analytically show that mesonic bound states of confined monopoles appear inside a non-Abelian vortex string in massless three-flavor QCD at large quark chemical potential μ. The orientational modes CP2 in the internal space of a vortex is described by the low-energy effective world-sheet theory. Mesons of confined monopoles are dynamically generated as bound states of kinks by the quantum effects in the effective theory. The mass of monopoles is shown to be an exponentially soft scale M∼Δexp[c(μ/Δ) 2], with the color superconducting gap Δ and some constant c. A possible quark-monopole duality between the hadron phase and the color superconducting phase is also discussed.
