喷流和高能光子通过夸克-胶子等离子体产生的中等质量双轻子

Intermediate mass dileptons from the passage of jets and high energy photons through quark-gluon plasma

Fu Yong-Ping, Li Yun-De

摘要:

计算了通过夸克-胶子等离子体的喷流和高能光子(分辨光子)的湮灭和康普顿散射产生的中等质量双轻子。由于喷流-等离子体和高能光子-等离子体相互作用的双轻子产额的贡献是显着的相比,在中间质量的热和Drell-Yan双轻子谱。热过程和Drell-Yan过程的普通谱被喷流和光子等离子体机制增强。计算结果与PHENIX数据在RHIC中质量区的Au-Au 200 GeV/A碰撞结果吻合较好。

英文摘要:

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.
