在LHC的胶子饱和和包含强子产生

Gluon saturation and inclusive hadron production at LHC

Eugene Levin, Amir H. Rezaeian

摘要:

在高密度QCD中,强子的产生源于具有饱和标度量级横动量的微喷注的衰变。本文表明,这一想法是能够在一个独特的方式来描述的包容性强子生产的\sqrt{s} \geq 546 GeV,包括第一个数据从LHC和深非弹性散射在HERA。我们的方法很好地描述了最近报道的ALICE、CMS和ATLAS的数据,包括pp碰撞中的带电强子横动量和多重数分布。我们为即将到来的LHC测量提供预测。

英文摘要:

In high density QCD the hadron production stems from decay of mini-jets that have the transverse momenta of the order of the saturation scale. It is shown in this paper that this idea is able to describe in a unique fashion both the inclusive hadron production for \sqrt{s} \geq 546 GeV including the first data from LHC and the deep inelastic scattering at HERA. Recently reported data from ALICE, CMS and ATLAS including inclusive charged-hadron transverse-momentum and multiplicity distribution in pp collisions are well described in our approach. We provide predictions for the upcoming LHC measurements.
