从SIDIS单横自旋不对称性中逐点提取部分子分布函数

Point-by-point extraction of parton distribution functions from SIDIS single transverse-spin asymmetries

Anna Martin, Franco Bradamante, Vincenzo Barone

摘要:

我们展示了如何从质子和氘核观测值的组合中逐点提取与核子横自旋相关的部分子分布函数。特别是,我们提出了一个确定的价和海Sivers功能的单自旋不对称性测量的COMPASS。

英文摘要:

We show how some parton distribution functions related to the transverse spin of nucleons can be extracted point by point from combinations of proton and deuteron observables. In particular, we present a determination of the valence and sea Sivers functions from the single-spin asymmetries measured by COMPASS.
