标题： Semihard Interactions in Nuclear Collisions Based on a Unified Approach to High Energy Scattering

摘要： 我们的最终目标是构建一个模型，用于描述在质心系中每核子能量范围从几十GeV到几TeV的两个核之间的相互作用。 这种核碰撞非常复杂，由许多组成部分构成，因此需要一种策略来构建一个可靠的模型。 我们方法的核心点是假设高能相互作用的行为是普遍的（普遍性假设）。 因此，例如，核相互作用中部分子的强子化遵循与电子-正电子湮灭中相同的规则；核碰撞中非定域部分子的辐射基于与深度非弹性散射中相同的原理。 我们以模块化的方式构建核相互作用的模型。 基于普遍性假设的各个模块被识别为更基本相互作用（如e^+ e^-、轻子-质子）的构建模块，因此可以在更简单的背景下进行研究。 掌握了这些构建模块后，我们可以提供一个相当可靠的核-核散射模型，特别是可以利用蒙特卡罗技术对复杂的数值过程进行非常有用的测试。 显示英文摘要

摘要： Our ultimate goal is the construction of a model for interactions of two nuclei in the energy range between several tens of GeV up to several TeV per nucleon in the centre-of-mass system. Such nuclear collisions are very complex, being composed of many components, and therefore some strategy is needed to construct a reliable model. The central point of our approach is the hypothesis, that the behavior of high energy interactions is universal (universality hypothesis). So, for example, the hadronization of partons in nuclear interactions follows the same rules as the one in electron-positron annihilation; the radiation of off-shell partons in nuclear collisions is based on the same principles as the one in deep inelastic scattering. We construct a model for nuclear interactions in a modular fashion. The individual modules, based on the universality hypothesis, are identified as building blocks for more elementary interactions (like e^+ e^-, lepton-proton), and can therefore be studied in a much simpler context. With these building blocks under control, we can provide a quite reliable model for nucleus-nucleus scattering, providing in particular very useful tests for the complicated numerical procedures using Monte Carlo techniques.
