我们提出了一种利用色偶极子模型将高能喷流蒙特卡罗产生的多部子态与Ariadne程序产生的部分子簇射相匹配的方法。高能喷射计划已经包括全面恢复软分歧。因此,在匹配中,重要的是减去部分子簇射中相应的发散,只保留共线部分。我们提出了一种新颖的、不依赖于淋浴的方法来实现这一点,使我们能够在强子碰撞中产生具有多个硬喷流的完全独占的强子化事件。我们通过实例详细讨论了纯QCD喷注产生的软区、共线区和硬区的描述。
We present a method to match the multi-parton states generated by the High Energy Jets Monte Carlo with parton showers generated by the Ariadne program using the colour dipole model. The High Energy Jets program already includes a full resummation of soft divergences. Hence, in the matching it is important that the corresponding divergences in the parton shower are subtracted, keeping only the collinear parts. We present a novel, shower-independent method for achieving this, enabling us to generate fully exclusive and hadronized events with multiple hard jets, in hadronic collisions. We discuss in detail the arising description of the soft, collinear and hard regions by examples in pure QCD jet-production.
