论文摘要
我们提出了一个简单的Parton-shower模型，该模型通过对方位角的非平凡依赖性，代替了相干分支形式主义的明确分支形式主义的显式秩序。我们介绍了全球运动学映射，并提供了一个分析证明，表明它符合临近领先的对数准确性的标准。在新算法中，初始和最终状态进化在相同的基础上进行处理。我们为数值代码Alaric提供了最终状态演化的实现，并与实验数据进行了首次比较。
We present a simple parton-shower model that replaces the explicit angular ordering of the coherent branching formalism with a differentially accurate simulation of soft-gluon radiation by means of a non-trivial dependence on azimuthal angles. We introduce a global kinematics mapping and provide an analytic proof that it satisfies the criteria for next-to leading logarithmic accuracy. In the new algorithm, initial and final state evolution are treated on the same footing. We provide an implementation for final-state evolution in the numerical code Alaric and present a first comparison to experimental data.
