Description
We investigate the fluctuation effects of a gap parameter in color superconductors. The fluctuation modes are described as the collective motion of a diquark field. One of the modes is a massless Nambu-Goldstone boson and the other is a diquark boson whose mass is twice the gap energy. It is also shown that in the normal phase the fluctuation mode becomes a precursory (soft) mode whose mass and decay width are calculated near the critical temperature. We discuss the temperature dependence of such quantities in detail
