论文摘要
我们介绍了一项研究对单粘合发射光谱的扩展对BDMPS-Z形式主义中射流抑制因子（$ q_ {aa} $）的影响。这些数量是针对三种类型的介质（静态培养基，指数衰减的培养基和Bjorken扩展介质）计算的。中诱导的胶子和JET $ q_ {aa} $的分布是使用对中等内部进化的评估，并通过源自Gluon发射光谱的分裂内核进行评估。在大型时代的渐近线中，针对低X和High-X机制得出了分裂内核的缩放行为及其对所得JET $ Q_ {AA} $的影响。对于辐射的整个相空间，提出了带有有效淬灭参数的JET $ Q_ {AA} $的缩放。
We present a study of the impact of the expansion of deconfined medium on single-gluon emission spectra and the jet suppression factor ($Q_{AA}$) within the BDMPS-Z formalism. These quantities are calculated for three types of media (static medium, exponentially decaying medium and Bjorken expanding medium). The distribution of medium-induced gluons and the jet $Q_{AA}$ are calculated using the evaluation of in-medium evolution with splitting kernels derived from the gluon emission spectra. Scaling behavior of splitting kernels is derived for low-x and high-x regimes in the asymptote of large times and its impact on the resulting jet $Q_{AA}$ is discussed. For the full phase space of the radiation, the scaling of jet $Q_{AA}$ with an effective quenching parameter is presented.
