基于一个相对论流体力学模型，在夸克-胶子等离子体中具有中等质量双轻子的产生被研究. 由于相边对夸克-胶子等离子体系统演化的影响和产生在RHIC能量的夸克-胶子等离子体系统有高的初始温度，夸克相的贡献变得比强子相互作用的贡献重要得多，甚至能与本底相比较. 它表明这样的增强是夸克-胶子等离子体形成的一种信号.

The production of dileptons in the intermediate mass region in QGP has been studied on the basis of a relativistic hydrodynamic model. Due to the influence of the phase boundary on the evolution of the QGP system and the high initial temperature of the QGP produced at RHIC energies, the quark phase contribution is much more important than that from hadronic interactions and even comparable with that from background sources. It is shown that such an enhancement is a signature for the QGP formation.
