大型强子对撞机前向喷流的产生

Forward Jet Production at the Large Hadron Collider

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

摘要:

在大型强子对撞机(LHC)上,通过高- $p_T$过程对强子-强子碰撞的前向区进行实验研究将首次成为可能。在LHC正向运动学中,硬横动量和大快度区间的QCD对数修正在数量上都是重要的。我们在QCD高能因子分解的框架下分析了前向喷注的强子产生,它允许我们一致地将两种修正恢复到QCD微扰理论中的高阶。我们计算短距离矩阵元素,以评估在完全排他的水平上的分解公式。我们讨论了编码在分解高能振幅中的大角度多胶子辐射的数值动力学特征。

英文摘要:

At the Large Hadron Collider (LHC) it will become possible for the first time to investigate experimentally the forward region in hadron-hadron collisions via high-$p_T$ processes. In the LHC forward kinematics QCD logarithmic corrections in the hard transverse momentum and in the large rapidity interval may both be quantitatively significant. We analyze the hadroproduction of forward jets in the framework of QCD high-energy factorization, which allows one to resum consistently both kinds of corrections to higher orders in QCD perturbation theory. We compute the short-distance matrix elements needed to evaluate the factorization formula at fully exclusive level. We discuss numerically dynamical features of multi-gluon emission at large angle encoded in the factorizing high-energy amplitudes.
