论文摘要
不同类型的高能量硬探针用于提取在重离子碰撞中产生的夸克 - 胶子等离子体的喷气运输特性，由于其干净的衰变签名和生产机制，重型玻色子标记的喷气机无疑是最复杂的。在这项研究中，我们使用重新召集改进的PQCD方法在硬质量上进行了高阶校正，以计算动量比率$ x_j $分布的$ z $和higgs（$ h $）标记的喷气机。我们发现形式主义可以很好地描述5.02 TEV $ PP $数据。使用BDMPS能量损失形式主义，以及OSU 2+1D水电来模拟培养基的效果，我们提取了喷气运输系数的价值，约为$ \ hat {q} _0 = 4 \ sim8〜gev^2/fm $，通过与$+Z $ z $ z $ z $ z $ z $+jet $ pbpb $实验数据进行比较。相比之下，$ H $+JET $ X_J $发行版的计算方式与$ Z $+喷气发行版相比，发现具有更强的Sudakov效果。这项研究使用干净的颜色中性玻色子作为研究喷射淬火效应的触发因素，并用作提取QGP运输系数在高能核碰撞中的互补方法。
Different types of high energy hard probes are used to extract the jet transport properties of the Quark-Gluon Plasma created in heavy-ion collisions, of which the heavy boson tagged jets are undoubtedly the most sophisticated due to its clean decay signature and production mechanism. In this study, we used the resummation improved pQCD approach with high order correction in the hard factor to calculate the momentum ratio $x_J$ distributions of $Z$ and Higgs($H$) tagged jets. We found that the formalism can provide a good description of the 5.02 TeV $pp$ data. Using the BDMPS energy loss formalism, along with the OSU 2+1D hydro to simulate the effect of the medium, we extracted the value of the jet transport coefficient to be around $\hat{q}_0=4\sim8~GeV^2/fm$ by comparing with the $Z$+jet $PbPb$ experimental data. The $H$+jet $x_J$ distribution were calculated in a similar manner in contrast and found to have a stronger Sudakov effect as compared with the $Z$+jet distribution. This study uses a clean color-neutral boson as trigger to study the jet quenching effect and serves as a complimentary method in the extraction of the QGP's transport coefficient in high energy nuclear collisions.
