论文摘要
奇怪的增强和集体流程被认为是夸克gluon血浆形成的特征。这些现象不仅在相对论的重离子碰撞中被检测到，而且在高能量，质子 - 普罗顿和质子核（小型系统）散射的高多样性事件中也被检测到。通过将横向平面中的Parton密度视为指定碰撞初始条件的动态量来出现普遍行为，在可用能量的电子峰值中，这种情况太低而无法期望集体效应。
Strangeness enhancement and collective flow are considered signatures of the quark gluon plasma formation. These phenomena have been detected not only in relativistic heavy ion collisions but also in high energy, high multiplicity events of proton-proton and proton-nucleus (small systems) scatterings. A universal behavior emerges by considering the parton density in the transverse plane as the dynamical quantity to specify the initial condition of the collisions, which in electron-positron annihilation at the available energies is too low to expect collective effects.
