$\sqrt{s}$ =14 TeV pp碰撞中修正Knudsen模型和椭圆流
Modified Knudsen ansatz and elliptic flow in $\sqrt{s}$=14 TeV pp collisions
摘要：
假设在初始pp碰撞中形成热点，在修正的Knudsen模型中，考虑粘性流体演化中的熵产生，我们给出了$\sqrt{s}$ =14 TeV pp碰撞中椭圆流的预言.预测流量取决于热点的数量和热点大小。如果在初始pp碰撞中形成2 ~ 4个$\approx$ 0.1 fm的热点，在多重数为$n_ {mult}\approx$ 10-15的事件中，修正的Knudsen模型预测的流动在四阶累积量方法中是可以实验得到的。
英文摘要：
Assuming that hot spots are formed in initial pp collisions, in a modified Knudsen ansatz, which accounts for the entropy generation in viscous fluid evolution, we have given predictions for elliptic flow in $\sqrt{s}$=14 TeV pp collisions. Predicted flow depends on the number of hot spots and hot spot sizes. If two to four hot spots of size $\approx$0.1 fm are formed in initial pp collisions, in events with multiplicity $n_ {mult}\approx$10-15, modified Knudsen ansatz predicted flow is accessible experimentally in 4th order cumulant method.
