彩色玻璃凝聚体中RHIC区d+Au碰撞中前向双强子的方位角关联

Azimuthal correlations of forward di-hadrons in d+Au collisions at RHIC in the Color Glass Condensate

Javier L. Albacete, Cyrille Marquet

摘要:

我们提出了一个很好的描述最近的实验数据,在RHIC的氘-金碰撞中测得的正向双强子方位角相关性,其中单喷流生产已被观察到。我们的方法是基于彩色玻璃凝聚有效理论的小x自由度的核波函数,包括使用非线性演化方程与运行QCD耦合。我们的分析为RHIC数据中饱和效应的存在提供了进一步的证据。

英文摘要:

We present a good description of recent experimental data on forward di-hadron azimuthal correlations measured in deuteron-gold collisions at RHIC, where monojet production has been observed. Our approach is based on the Color Glass Condensate effective theory for the small-x degrees of freedom of the nuclear wave function, including the use of non-linear evolution equations with running QCD coupling. Our analysis provides further evidence for the presence of saturation effects in RHIC data.
