大型强子对撞机上夸克-强子相变的可观测性质
Observable Properties of Quark-Hadron Phase Transition at the Large Hadron Collider
摘要：
夸克-强子相变是由一个事件发生器模拟的，它包含了由于QCD约束力的收缩和由于强子化边缘的大夸克系统的热行为的随机化的动力学性质。在$(η,ϕ)$空间发射π介子的波动进行了分析，使用归一化阶乘矩在很宽的范围内的bin大小。标度指数$ν$被发现是非常接近的预测值在Ginzburg-Landau形式主义。不规则性指数$μ_q$以多种方式确定，这些方式导致相同的一致值。将它们与来自伊辛模型的值进行比较，在透明图中显示显著差异。为了检验理论研究的真实性，并为改进夸克-强子相变的模型描述提供指导，需要在LHC上对$ν$和$μ_q$进行实验测定。
英文摘要：
Quark-hadron phase transition is simulated by an event generator that incorporates the dynamical properties of contraction due to QCD confinement forces and randomization due to the thermal behavior of a large quark system on the edge of hadronization. Fluctuations of emitted pions in the $(η,ϕ)$ space are analyzed using normalized factorial moments in a wide range of bin sizes. The scaling index $ν$ is found to be very close to the predicted value in the Ginzburg-Landau formalism. The erraticity indices $μ_q$ are determined in a number of ways that lead to the same consistent values. They are compared to the values from the Ising model, showing significant difference in a transparent plot. Experimental determination of $ν$ and $μ_q$ at the LHC are now needed to check the reality of the theoretical study and to provide guidance for improving the model description of quark-hadron phase transition.
