QCD喷流及其它喷流中的三粒子关联

Three-particle correlations in QCD jets and beyond

Redamy Perez Ramos, Vincent Mathieu, Miguel-Angel Sanchis-Lozano

摘要:

在本文中,我们提出了一个更详细的版本,我们以前的工作在夸克和胶子喷注中的三粒子关联[1]。我们给出了双对数近似和修正的领先对数近似下的理论结果。在这两个remation计划,我们使用的形式主义的生成功能和解决的演化方程解析从最速下降评估的单粒子分布。此外,在本文中,我们包括超出极限谱近似的预测,并研究这个可观察到的驼峰附近的单一包容性分布。因此,我们提供了进一步的测试局域部分子强子对偶性(LPHD),并作出预测的LHC。高阶算子的计算是在双对数近似下提出的,并且相当麻烦。

英文摘要:

In this paper, we present a more detailed version of our previous work for three-particle correlations in quark and gluon jets [1]. We give theoretical results for this observable in the double logarithmic approximation and the modified leading logarithmic approximation. In both resummation schemes, we use the formalism of the generating functional and solve the evolution equations analytically from the steepest descent evaluation of the one-particle distribution. In addition, in this paper we include predictions beyond the limiting spectrum approximation and study this observable near the hump of the single inclusive distribution. We thus provide a further test of the local parton hadron duality (LPHD) and make predictions for the LHC. The computation of higher rank correlators is presented in the double logarithmic approximation and shown to be rather cumbersome.
