论文摘要
Using the CUJET3=DGLV+VISHNU jet-medium interaction framework, we show that dijet azimuthal acoplanarity in high energy $A+A$ collisions is sensitive to possible non-perturbative enhancement of the jet transport coefficient, $\hat{q}(T,E)$, in the QCD crossover temperature $T\sim 150-300$ MeV range.由于$ r_ {aa} $的核修改数据，我们的核耦合被限制为全球rhic \＆lhc $χ^2 $，我们比较了中等诱导的Dijet Dijet横向动量平方的预测，$ q_S^2 \ sim \ sim \ sim \ sim \ sim \ langle \ hat {q} l \ rangle \ sim $ sim^$ sim^2 $ tw $和喷气中型传输系数的Jet Energy $ E $依赖性，$ \ hat {q}（t，e）$。在一个模型中，仅假定仅假定扰动夸克和gluon dof。在第二个模型中，SQGMP，非扰动三个成分半夸克 - 胶状和磁性单极DOF被弄小了。我们表明，Dijet Path平均培养基引起的方位型螺旋体，$ δϕ^2 $，在SQGMP中，较强的$ \ sim 2 $比在扰动WQGP中大，而两种模型中的辐射能量损失几乎与同一单型核修饰$ r _ fit fit两种模型几乎相同。 Future A+A Dijet Acoplanarity测量值与$ R_ {AA} $和Azimuthal不对称$ V_N $测量相关，似乎是一种有希望的策略，可以在QCD限制温度范围内寻找关键蛋白质类似现象的可能标志。
Using the CUJET3=DGLV+VISHNU jet-medium interaction framework, we show that dijet azimuthal acoplanarity in high energy $A+A$ collisions is sensitive to possible non-perturbative enhancement of the jet transport coefficient, $\hat{q}(T,E)$, in the QCD crossover temperature $T\sim 150-300$ MeV range. With jet-medium couplings constrained by global RHIC\& LHC $χ^2$ fits to nuclear modification data on $R_{AA}$, we compare predictions of the medium induced dijet transverse momentum squared, $Q_s^2\sim \langle \hat{q} L \rangle \sim Δϕ^2 E^2$, in two models of the temperature, $T$, and jet energy $E$ dependence of the jet medium transport coefficient, $\hat{q}(T,E)$. In one model, wQGP, only perturbative quark and gluon dof are assumed. In the second model, sQGMP, nonperturbative three component semi-Quark-Gluon and Magnetic Monopole dof are asssumed. We show that the dijet path averaged medium induced azimuthal acoplanarity, $Δϕ^2$, in sQGMP is robustly a factor of $\sim 2$ larger than in perturbative wQGP while the radiative energy loss in both models is nearly identical as required to fit the same single jet nuclear modification $R_{AA}$ data. Future A+A dijet acoplanarity measurements correlated with $R_{AA}$ and azimuthal asymmetry $v_n$ measurements therefore appears to be a promising strategy to search for possible signatures of critical opalescence like phenomena in the QCD confinement temperature range.
