标题： Deep-Inelastic Final States in a Space-Time Description of Shower Development and Hadronization

摘要： 我们扩展了一种量子动力学方法来描述空间、时间和动量空间中的强子簇射，将其应用于深部非弹性碰撞$ep$，特别是针对 HERA 实验。 我们追溯硬散射事件的历史，从初始的强子状态回溯到最终形成颜色单态的强子前驱团簇及其衰变为强子。 类似地，处理了时空初始态簇射和时间型次级部分子的时间演化，使用由禁闭启发的空间判据以及一个非微扰的强子化模型来处理团簇形成。 我们计算了粒子在快速性、横向和纵向空间中的分布随时间的演化。 此外，我们将横向强子能量流和观测到的强子质量分布与 HERA 的实验数据进行了比较，得到了令人鼓舞的结果。 本文开发的技术未来可以应用于更复杂的过程，如 eA、pp、pA 和 AA 碰撞等。 显示英文摘要

摘要： We extend a quantum kinetic approach to the description of hadronic showers in space, time and momentum space to deep-inelastic $ep$ collisions, with particular reference to experiments at HERA. We follow the history of hard scattering events back to the initial hadronic state and forward to the formation of colour-singlet pre-hadronic clusters and their decays into hadrons. The time evolution of the space-like initial-state shower and the time-like secondary partons are treated similarly, and cluster formation is treated using a spatial criterion motivated by confinement and a non-perturbative model for hadronization. We calculate the time evolution of particle distributions in rapidity, transverse and longitudinal space. We also compare the transverse hadronic energy flow and the distribution of observed hadronic masses with experimental data from HERA, and find encouraging results. The techniques developed in this paper may be applied in the future to more complicated processes such as eA, pp, pA and AA collisions.
