量子干涉下的部分子簇射:主导色,自旋

Parton showers with quantum interference: leading color, with spin

Zoltan Nagy, Davison E. Soper

摘要:

我们以前描述了一个部分子簇射的数学公式的基础上近似的强有序虚连续的部分子分裂。量子干涉,包括不同颜色和自旋状态之间的干涉。一个实际的数字执行战略没有具体说明。在随后的一篇论文中,我们证明了如果我们增加只取主导色限和对自旋平均的进一步近似,我们得到了一个可以实现为马尔可夫过程的簇射演化。在本文中,我们概述了一种策略,包括部分子自旋引起的相关性。

英文摘要:

We have previously described a mathematical formulation for a parton shower based on the approximation of strongly ordered virtualities of successive parton splittings. Quantum interference, including interference among different color and spin states, was included. A practical numerical implementation strategy was left unspecified. In a subsequent paper, we showed that if we add the further approximations of taking only the leading color limit and averaging over spins, we obtain a shower evolution that can be implemented as a Markov process. In this paper, we outline a strategy for including the correlations induced by parton spins.
