GPD和TMD之间的关系:模型结果及其他

Relations between GPDs and TMDs: model results and beyond

S. Meissner, A. Metz, M. Schlegel, K. Goeke

摘要:

比较定义广义和横向动量相关部分子分布的两种不同的量子化子的结构,可以发现这两种物质之间可能存在的联系。虽然它看起来像发现的关系一般不成立,我们表明,他们至少可以建立在简单的旁观者模型计算。此外,我们讨论了这些关系的广义横向动量依赖部分子分布的背景下。

英文摘要:

Comparing the respective structures of the correlators defining generalized and transverse momentum dependent parton distributions, one finds possible relations between these two objects. Although it looks like the relations found do not hold in general, we show that they can be established at least in simple spectator model calculations. In addition, we discuss these relations in the context of generalized transverse momentum dependent parton distributions.
