Abstract
We explore how the dilepton production rate is modified by the diquark fluctuations that form well-developed collective modes near but above the critical temperature of color superconductivity. Through the analysis of the photon self-energy called the Aslamasov-Larkin, Maki-Thompson and density of states terms which are known in the metalic superconductivity, it is shown that the diquark fluctuation mode affects the photon self-energy significantly and thereby cause to anomalously enhance the dilepton production rate in the low invariant-mass region.
