论文摘要
我们对$ pp $碰撞中有和没有夸克 - 胶状等离子体形成的场景的重型风味进行了针对重型风味的喷气淬火的实验数据进行全球分析。我们发现，在LHC Energies中，核修饰因子$ r_ {aa} $的理论预测在这些情况下非常相似，并且$ r_ {aa} $的结果和$ v_2 $的结果与LHC数据合理地同意。对于中间场景，与RHIC Top Energy的数据达成协议变得更好，在该场景中，夸克 - 格鲁恩等离子体形成$ pp $碰撞仅发生在LHC Energies。我们适合重味的$ r_ {aa} $，显示了对重型口味的喷气淬火的描述，需要$α_s$比亮光的Quenching的数据更大。
We perform a global analysis of experimental data on jet quenching for heavy flavors for scenarios with and without quark-gluon plasma formation in $pp$ collisions. We find that the theoretical predictions for the nuclear modification factor $R_{AA}$ for heavy flavors at the LHC energies are very similar for these scenarios, and the results for $R_{AA}$ and $v_2$ agree reasonably with the LHC data. The agreement with data at the RHIC top energy becomes somewhat better for the intermediate scenario, in which the quark-gluon plasma formation in $pp$ collisions occurs only at the LHC energies. Our fits to heavy flavor $R_{AA}$ show that description of jet quenching for heavy flavors requires somewhat bigger $α_s$ than data on jet quenching for light hadrons.
