大型强子对撞机的前向中心喷流关联

Forward-Central Jet Correlations at the Large Hadron Collider

M. Deak, F. Hautmann, H. Jung, K. Kutak

摘要:

对于大型强子对撞机(LHC)上的高pT正演过程,在硬横动量和大快度区间的QCD对数修正可能都是定量重要的。在微扰论中将两种对数修正一致地恢复到高阶的理论框架是基于QCD高能因子分解。我们提出了数值蒙特卡罗应用这种方法与生产的一个前进和一个中央喷流的最终状态观测。通过计算喷流在快度和方位角的相关性,我们分析了大角度胶子辐射对部分子簇射链的修正的作用,并讨论了这与Monte Carlo模拟多个部分子链相互作用的结果的关系。

英文摘要:

For high-pT forward processes at the Large Hadron Collider (LHC), QCD logarithmic corrections in the hard transverse momentum and in the large rapidity interval may both be quantitatively significant. The theoretical framework to resum consistently both kinds of logarithmic corrections to higher orders in perturbation theory is based on QCD high-energy factorization. We present numerical Monte Carlo applications of this method to final-state observables associated with production of one forward and one central jet. By computing jet correlations in rapidity and azimuth, we analyze the role of corrections to the parton-showering chain from large-angle gluon radiation, and discuss this in relationship with Monte Carlo results modeling interactions due to multiple parton chains.
