论文摘要
Herwig 7是粒子碰撞的通用蒙特卡洛发生器，包括硬扰动和软现象物理学。因此，赫维格能够在碰撞事件中描述整个强膦颗粒的最终状态。首次对Parton系统进入强环化的时空拓扑结构首次完全描述和测试。来自颗粒动量和时空位置的信息的组合可最大程度地减少Parton系统的增强不变距离度量。我们提出了该模型的合理协议，并选择了一系列实验数据，并得出结论，时空事件拓扑可以有意义地用于进一步的开发中。
Herwig 7 is a general-purpose Monte Carlo generator of particle collisions comprising both hard perturbative as well as soft phenomenological physics. Herwig is therefore capable to describe the entire final state of hadronized particles in a collision event. A spacetime topology of a parton system entering hadronization is fully described and tested for the first time. A combination of information from particles momenta and spacetime positions is utilized to minimize a boost-invariant distance measure of the parton system. We present a reasonable agreement of the model with a selection of experimental data and conclude that spacetime event topology can be meaningfully used in the further development.
