A. Sibirtsev, H. -W. Hammer, U. -G. Meissner

摘要:

本文系统地分析了质子-核碰撞中φ介子产生的A依赖性。我们应用不同的形式来计算核中的φ介子畸变,并讨论了数据分析的理论不确定性。相应的结果进行了比较,理论预测。我们还讨论了解释提取的结果与不同的可观测量,并提供经常使用的定义之间的关系。展望未来的实验进行了评估和估计的基础上,我们的系统研究。

英文摘要:

A systematic analysis of the A-dependence of phi-meson production in proton-nucleus collisions is presented. We apply different formalisms for the evaluation of the phi-meson distortion in nuclei and discuss the theoretical uncertainties of the data analysis. The corresponding results are compared to theoretical predictions. We also discuss the interpretation of the extracted results with respect to different observables and provide relations between frequently used definitions. The perspectives of future experiments are evaluated and estimates based on our systematical study are given.
