论文摘要
我们表明，高$ p_t $ $ $ r_ {aa} $和$ v_2 $对早期的扩展动态很敏感，并且高$ p_t $可观察力更喜欢延迟能量损失和横向扩展。要计算高$ p_t $ $ $ r_ {aa} $和$ v_2 $，我们采用了新开发的dreena-A框架，该框架将最新的动态能量损失模型与3+1维水力动力学模拟结合在一起。该模型既适用于浅色和浓重的风味，我们预测横向膨胀的发作对重风味的敏感性更大。这是第一次由高质量QGP行为受到高$ p_ \ perp $可观察理论的限制，即通过所谓的QGP断层扫描。
We show that high-$p_T$ $R_{AA}$ and $v_2$ are sensitive to the early expansion dynamics, and that the high-$p_T$ observables prefer delayed onset of energy loss and transverse expansion. To calculate high-$p_T$ $R_{AA}$ and $v_2$, we employ our newly developed DREENA-A framework, which combines state-of-the-art dynamical energy loss model with 3+1-dimensional hydrodynamical simulations. The model applies to both light and heavy flavor, and we predict a larger sensitivity of heavy flavor observables to the onset of transverse expansion. This presents the first time when bulk QGP behavior has been constrained by high-$p_\perp$ observables and related theory, i.e., by so-called QGP tomography.
