论文摘要
重型离子碰撞中的部分与夸克 - 胶状等离子体（QGP）相互作用，因此与真空相比，其能量和淋浴结构修改了。理论计算预测，辐射能量损失是QGP中胶子和光夸克的主要能量损失模式，对于低横向动量处的重夸克（$ p _ {\ text {t}} $）被抑制。在RHIC能量中，更接近魅力夸克质量的较低能量喷气机更容易获得，并且可以为理解Parton能量损失的质量依赖性提供重要的见解。我们报告了$ d^{0}（c \ bar {u}）$ Meson标记的第一个测量值\ text {gev} $，由星实验收集。
Partons in heavy-ion collisions interact strongly with the Quark-Gluon Plasma (QGP), and hence have their energy and shower structure modified compared to those in vacuum. Theoretical calculations predict that the radiative energy loss, which is the dominant mode of energy loss for gluons and light quarks in the QGP, is suppressed for heavy quarks at low transverse momenta ($p_{\text{T}}$). At RHIC energies, lower energy jets closer to the charm quark mass are more accessible, and could provide key insight into the understanding of the mass dependence of parton energy loss. We report the first measurements of the $D^{0} (c\bar{u})$ meson tagged jet $p_{\text{T}}$ spectra and the $D^{0}$ meson radial profile in jets reconstructed from Au+Au collisions at $\sqrt{s_{\text{NN}}} = 200 \text{ GeV}$, collected by the STAR experiment.
