质子-质子和质子-核碰撞中有色玻璃凝聚与双强子关联的比较

Comparison of the Color Glass Condensate to di-hadron correlations in proton-proton and proton-nucleus collisions

Kevin Dusling, Raju Venugopalan

摘要:

我们进行了详细的比较的长程快度相关的彩色玻璃凝聚框架中的质子-质子和质子-铅碰撞的CMS,ALICE和ATLAS实验在LHC的高多重性双强子数据。到目前为止,理论与数据的非平凡系统学的总体良好一致性强烈暗示了胶子饱和和快度分离胶子之间存在微妙的量子干涉效应。特别是,在相对方位角$Δϕ\sim 0$上准直的电子对的产额对强子中未积分胶子分布的形状敏感,这些强子是从束流快度到被测强子快度的快速演化的重整化群。我们目前的估计,预计在中央氘-金碰撞在RHIC的准直双强子产额。

英文摘要:

We perform a detailed comparison of long range rapidity correlations in the Color Glass Condensate framework to high multiplicity di-hadron data in proton-proton and proton-lead collisions from the CMS, ALICE and ATLAS experiments at the LHC. The overall good agreement thus far of the non-trivial systematics of theory with data is strongly suggestive of gluon saturation and the presence of subtle quantum interference effects between rapidity separated gluons. In particular, the yield of pairs collimated in their relative azimuthal angle $Δϕ\sim 0$, is sensitive to the shape of unintegrated gluon distributions in the hadrons that are renormalization group evolved in rapidity from the beam rapidities to those of the measured hadrons. We present estimates for the collimated di-hadron yield expected in central deuteron-gold collisions at RHIC.
