High energy QCD: Multiplicity distribution and entanglement entropy

In this paper we show that QCD at high energies leads to the multiplicity distribution $\frac{\sigma_n}{\sigma_{ \rm in}}\,\,= \,\,\frac{1}{N}\,\Lb \frac{N\,-\,1}{N}\Rb^{n - 1}$, (where denotes the average number of particles), and to entanglement entropy , confirming that the partonic state at high energy is maximally entangled. However, the value of depends on the kinematics of the parton cascade. In particular, for DIS , where is the gluon structure function, while for hadron-hadron collisions, , where denotes the saturation scale. We checked that this multiplicity distribution describes the LHC data for low multiplicities $n ,

高能QCD:多重分布和纠缠熵
在本文中,我们证明高能量的QCD导致多重分布$ \ frac {\ sigma_n} {\ sigma_ {\ rm in}} \,\,= \,\,\ frac {1} {N} \, \ Lb \ frac {N \,-\,1} {N} \ Rb ^ {n-1} $,(其中 表示平均粒子数),并纠缠熵 ,证实了高能量下的部分状态被最大程度地纠缠了。但是, 取决于parton级联的运动学。特别是对于DIS ,在哪里 是胶子结构函数,而对于强子-强子碰撞, ,在哪里 表示饱和度标度。我们检查了该多重性分布是否描述了低多重性$ n的LHC数据,
