色散关系在硬排斥过程中的应用及虚康普顿散射的部分解释

The Use of Dispersion Relations in Hard Exclusive Processes and the Partonic Interpretation of Deeply Virtual Compton Scattering

Gary R. Goldstein, Simonetta Liuti

摘要:

最近的色散关系已被应用到硬排他性的过程,如深虚拟康普顿散射,全息原理,提出了映射的广义部分子分布进入软矩阵元素的过程,从它们的值在一个给定的运动学脊。我们检查可能的陷阱与隐式的,直接识别在这种方法中的物理强子状态与有色部分子,并提出了一个改进的治疗这一假设。

英文摘要:

Recently dispersion relations have been applied to hard exclusive processes such as deeply virtual Compton scattering, and a holographic principle was proposed that maps out the generalized parton distributions entering the soft matrix elements for the processes from their values on a given kinematical ridge. We examine possible pitfalls associated with the implicit, direct identification in this approach of the physical hadronic states with colored partons, and suggest an improved treatment of this assumption.
