质子自旋之谜:我们今天在哪里?

The proton spin puzzle: where are we today ?

Steven D. Bass

摘要:

在过去的20年里,质子自旋之谜挑战了我们对QCD的理解。极化胶,价和海夸克极化,包括奇怪的夸克极化的新的测量,是可用的。这些数据中有什么新的和令人兴奋的,这可能告诉我们关于质子结构的什么?质子自旋之谜似乎在告诉我们价夸克与QCD复杂真空结构的相互作用。

英文摘要:

The proton spin puzzle has challenged our understanding of QCD for the last 20 years. New measurements of polarized glue, valence and sea quark polarization, including strange quark polarization, are available. What is new and exciting in the data, and what might this tell us about the structure of the proton ? The proton spin puzzle seems to be telling us about the interplay of valence quarks with the complex vacuum structure of QCD.
