论文摘要
引入40年后，色彩透明度的现象仍然是实验数据的有争议解释的领域。我们审查了在各种独家硬散射反应中表现出来的证据或反对其表现的证据。核透明度实验揭示了短距离过程是否在某些给定的运动点上占主导地位。我们恳求在各种实验设置中进行新的核透明度测量，包括与通用Parton分布（GPD）物理学有关的接近前进的独家反应和与过渡分布振幅（TDA）物理学有关的接近回避的独家反应。
40 years after its introduction, the phenomenon of color transparency remains a domain of controversial interpretations of experimental data. We review present evidence for or against its manifestation in various exclusive hard scattering reactions. The nuclear transparency experiments reveal whether short distance processes dominate a scattering amplitude at some given kinematical point. We plead for a new round of nuclear transparency measurements in a variety of experimental set-ups, including near-forward exclusive reactions related to generalized parton distribution (GPD) physics and near-backward exclusive reactions related to transition distribution amplitudes (TDA) physics.
