摘要:

重味探针对夸克-胶子等离子体的性质非常敏感,是等离子体层析成像研究的重要工具。前向快度观测值可以提供对介质动力学的进一步了解,这是由于介质大小和重夸克探针产生谱差异之间的相互作用。本文给出了B介子和D介子以及重味轻子在快度范围$-4.0 < y < 4.0$内的核修正因子$R_\text{AA}$。我们目前的比较与实验数据在中快度以及不同的快度范围内的预测。

英文摘要:

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.
