强子化与色透明

Hadronization and Color Transparency

Kai gallmeister, Ulrich Mosel

摘要:

本文综述了我们在核环境中强子产生方面的工作。我们的工作与弦断裂模型的强子的初始生产和量子动力学输运模型(GiBUU)来描述新形成的(前)强子的终态相互作用。后者是由强子-强子截面的形成时间和时间发展决定的。我们首先表明,只有一个线性的时间依赖性是能够描述可用的强子化数据。然后,我们比较详细的数据从HERMES和JLAB,非常好的协议是在所有的反应研究没有任何调整的参数。我们还重复的π介子和K介子在JLAB@12GeV的光谱预测。最后,我们解释了在最近的实验中没有CT效应的质子在准弹性(QE)事件对核的闪烁。我们建议,而不是寻找CT效应的质子在半包容性DIS(SIDIS)的事件。

英文摘要:

In this article we review our work on the production of hadrons in the nuclear environment. We work with a string-breaking model for the initial production of hadrons and with a quantum-kinetic transport model (GiBUU) to describe the final state interactions of the newly formed (pre)hadrons. The latter are determined both by the formation times and by the time-development of the hadron-hadron cross section. We first show that only a linear time-dependence is able to describe the available hadronization data. We then compare with detailed data from HERMES and JLAB; very good agreement is reached in all reactions studied without any tuning of parameters. We also repeat predictions of spectra for pions and kaons at JLAB@12GeV. We finally explain the absence of CT effects in the recent experiment on proton transparencies in quasielastic (QE) events on nuclei. We propose to look instead for CT effects on protons in semi-inclusive DIS (SIDIS) events.
