晶格上强子结构的研究

Investigations of hadron structure on the lattice

J. M. Zanotti

摘要:

强子结构的晶格模拟现在达到了一个水平,他们不仅能够补充,而且还提供指导,目前和即将到来的实验计划,如杰斐逊实验室,COMPASS/CERN和FAIR/GSI。在这次演讲中,我回顾了过去一年在这一令人兴奋的领域取得的进展,并讨论了我们可以期待在未来一年看到的进展。主题包括形状因子(包括过渡形状因子),普通部分子和广义部分子分布函数的矩,分布振幅的矩,以及磁极化和电极化。我还将强调在确定强子性质的不连续贡献方面所取得的进展。这里特别感兴趣的是奇异夸克对各种核子性质的贡献的大小。

英文摘要:

Lattice simulations of hadronic structure are now reaching a level where they are able to not only complement, but also provide guidance to current and forthcoming experimental programmes at, e.g. Jefferson Lab, COMPASS/CERN and FAIR/GSI. In this talk I review the progress that has been made in this exciting area in the past year and discuss the advances that we can expect to see in the coming year.Topics to be covered include form factors (including transition form factors), moments of ordinary parton and generalised parton distribution functions, moments of distribution amplitudes, and magnetic and electric polarisabilities. I will also highlight the progress being made in determining disconnected contributions to hadronic properties. Of particular interest here is the size of the contribution to various nucleonic properties coming from strange quarks.
