论文摘要
人们普遍认为，重型风味探针对Quark-Gluon血浆的特性敏感，并且通常被认为是血浆层析成像研究的重要工具。由于中等大小之间的相互作用和重型夸克探针的生产光谱之间的相互作用，远期快速性可观察到可以进一步了解培养基的动力学。在此程序中，我们介绍了B和D Meson的核修饰因子$ r_ \ text {aa} $，以及较重的风味leptons，在速度范围内，$ -4.0 <y <4.0 $从相对性的兰格文方程中获得的Gluon辐射与A（3+1）-Dimemensional Hydrodynics Mediamiss Medimandsicment相关。我们介绍了与中期的实验数据以及不同速度范围的预测。
It is widely acknowledged that heavy flavor probes are sensitive to the properties of the quark-gluon plasma and are often considered an important tool for the plasma tomography studies. Forward rapidity observables can provide further insight on the dynamics of the medium due to the interplay between the medium size and the differences in the production spectra of heavy quark probes. In this proceedings we present the nuclear modification factor $R_\text{AA}$'s for B and D mesons, as well as heavy flavor leptons, in the rapidity range $-4.0 < y < 4.0$ obtained from relativistic Langevin equation with gluon radiation coupled with a (3+1)-dimensional viscous hydrodynamics medium background. We present comparison with experimental data at mid-rapidity as well as predictions for different rapidity ranges.
