包容性视角

Inclusive Perspectives

Paul Hoyer

摘要:

我讨论了包含和排他性的动态之间的关系所建议的布卢姆吉尔曼对偶。对偶性意味着同时适用于两个不同的限制,标准的DIS限制硬包容性的过程中采取固定xB和限制强子质量是固定的。我审查的相关性的固定质量限制在包容性的过程中,在高xF的实验证据。半局域对偶性表明,包容性和排他性的过程发生在同一目标福克态。DIS缩放则意味着有助于硬互斥过程的Fock态具有大的横向尺寸,即,硬散射发生在携带大部分强子动量的单个部分子上。

英文摘要:

I discuss the relation between inclusive and exclusive dynamics suggested by Bloom-Gilman duality. Duality implies the simultaneous applicability of two distinct limits, the standard DIS limit of hard inclusive processes taken at fixed xB and a limit where the hadronic mass is held fixed. I review experimental evidence for the relevance of the fixed mass limit in inclusive processes at high xF. Semi-local duality suggests that inclusive and exclusive processes occur on the same target Fock states. DIS scaling then implies that the Fock states contributing to hard exclusive processes have a large transverse size, i.e., that the hard scattering occurs off a single parton which carries a large fraction of the hadron momentum.
