摘要:

我们研究的作用,纯粹的外部运动学近似在包容性的深度非弹性轻子-强子散射内QCD因式分解,并考虑因式分解与目标强子质量的精确治疗。我们讨论了如何观察到的现象学的改进,通过占目标质量运动学可以解释的目标结构的一般性质,并认为,这样的改进意味着一个层次的非微扰尺度内的强子。

英文摘要:

We study the role of purely external kinematical approximations in inclusive deep-inelastic lepton--hadron scattering within QCD factorization, and consider factorization with an exact treatment of the target hadron mass. We discuss how an observed phenomenological improvement obtained by accounting for target mass kinematics could be interpreted in terms of general properties of target structure, and argue that such an improvement implies a hierarchy of nonperturbative scales within the hadron.
