广义Parton分布的部分解释

Partonic Interpretation of Generalized Parton Distributions

Gary R. Goldstein, Simonetta Liuti

摘要:

广义Parton分布描述了在QCD分解中,深虚互斥过程振幅中的非微扰分量。然而,为了使部分音解释成立,半不连通图不应该有贡献。我们表明,这个条件是不满足非正向运动学在领先的顺序,胶子介导的重新相互作用是必不可少的一个一致的描述部分子自由度。

英文摘要:

Generalized Parton Distributions describe, within QCD factorization, the non perturbative component in the amplitudes for deeply virtual exclusive processes. However, in order for a partonic interpretation to hold, semi-disconnected diagrams should not contribute. We show that this condition is not satisfied for non-forward kinematics at leading order, and that gluon mediated re-interactions are essential for a consistent description in terms of parton degrees of freedom.
