pA碰撞中胶子饱和的研究

The Search for Gluon Saturation in pA Collisions

Bo-Wen Xiao

摘要:

在这次演讲中,我回顾了最近在RHIC和LHC上对$pA$碰撞中胶子饱和现象的理论研究进展。这一探索的两个重要支柱是单一的包容性向前强子生产和向前的双强子相关性,这两个都被计算到一个循环内的小$x$因式分解形式主义。此外,详细的数值研究的单包含强子生产次主导秩序为我们提供了很好的描述低横动量的数据测量在RHIC的$dAu$碰撞显着降低的不确定性。此外,对$pA$碰撞中双强子产生的单圈计算表明,在背靠背关联极限中存在一种新的大对数,称为Sudakov因子.

英文摘要:

In this talk, I reviewed the recent theoretical progress towards the exploration of the gluon saturation phenomenon in $pA$ collisions at both RHIC and the LHC. Two important pillars of this exploration are the single inclusive forward hadron productions and forward dihadron correlations, which have both been computed up to one-loop order within the small-$x$ factorization formalism. Furthermore, detailed numerical study for the single inclusive hadron production at next-to-leading order provides us good description of the low transverse momentum data measured in $dAu$ collisions at RHIC with significantly reduced uncertainty. In addition, the one-loop calculation for dihadron productions in $pA$ collisions shows that there is a new type of large logarithm, which is known as the Sudakov factor, arising in the back-to-back correlation limit.
