摘要:

在用协变动量分布描述部分子内禀运动的协变模型中,研究了核子的横向部分子动量相关分布函数。证明了该方法的一致性,并研究了TMD之间的模型关系。作为一个副产品,它示出了该方法如何允许制定的非相对论性的限制。

英文摘要:

Transverse parton momentum dependent distribution functions (TMDs) of the nucleon are studied in a covariant model, which describes the intrinsic motion of partons in terms of a covariant momentum distribution. The consistency of the approach is demonstrated, and model relations among TMDs are studied. As a byproduct it is shown how the approach allows to formulate the non-relativistic limit.
