论文摘要
我们计算了由于动态diquark波动而导致的光子自我能量的修饰，通过Aslamasov-larkin，Maki-Thompson和状态术语的密度在颜色超导的临界温度附近发展，这是导致能量和动量和动量和动量时金属副导管的。结果表明，在正常相的温度范围内，在低不变质量区域的速率在低不变质量区域具有显着增强。这种增强值得在相对论的重离子碰撞中探索，从而揭示了diquark波动在密集的夸克物质中的重要性。
We compute the modification of the photon self-energy due to dynamical diquark fluctuations developed near the critical temperature of the color superconductivity through the Aslamasov-Larkin, Maki-Thompson and density of states terms, which are responsible for the paraconductivity in metals at vanishing energy and momentum. It is shown that the rate has a significant enhancement at low invariant-mass region over a rather wide range of temperature in the normal phase. This enhancement is worth exploration in the relativistic heavy-ion collisions, which may thereby reveal the significance of the diquark fluctuations in dense quark matter.
