摘要:

在大型强子对撞机上的高多重数质子-质子碰撞可能会表现出集体现象,如椭圆流。我们研究这个问题使用DIPSY,一个全新的Monte Carlo事件发生器,其功能几乎NLO BFKL动力学和描述的质子的横向形状,包括所有的波动。我们预测的偏心率的碰撞作为多重性的函数,并估计椭圆流的大小。我们建议,流量可以通过信号的四粒子方位角相关的符号变化。

英文摘要:

High-multiplicity proton-proton collisions at the LHC may exhibit collective phenomena such as elliptic flow. We study this issue using DIPSY, a brand-new Monte Carlo event generator which features almost-NLO BFKL dynamics and describes the transverse shape of the proton including all fluctuations. We predict the eccentricity of the collision as a function of the multiplicity and estimate the magnitude of elliptic flow. We suggest that flow can be signaled by a sign change in the four-particle azimuthal correlation.
