摘要
从喷气和通过 quark-gluon 血浆的高精力光子(解决的光子) 散布的歼灭和康普顿发源的中间的集体 dileptons 的生产是计算的。dilepton 收益的贡献由于喷气血浆和高精力光子血浆相互作用被读与相比热并且在中间的质量的 Drell-Yan dilepton 光谱。平常的光谱热并且 Drell-Yan 过程被喷气和光子血浆机制提高。数字结果在 RHIC 为 Au-Au 200 GeV/A 碰撞在中间的集体区域精确地匹配到 PHENIX 数据。[从作者抽象]
The production of the intermediate mass dileptons originating from the annihilation and Compton scattering of the jets and high energy photons （resolved photons） passing through the quark-gluon plasma is calculated. The contribution of the dilepton yield due to the jet-plasma and high energy photon-plasma interaction is pronounced compared to the thermal and Drell-Yan dilepton spectrum at intermediate mass. The ordinary spectrum of thermal and Drell-Yan processes is enhanced by the jet and photon-plasma mechanism. The numerical results match to the PHENIX data accurately in the intermediate mass region for Au-Au 200 GeV/A collisions at RHIC.
