来自大型强子电子对撞机的nPDF约束

nPDF constraints from the Large Hadron Electron Collider

Ilkka Helenius, Hannu Paukkunen, Nestor Armesto

摘要:

对未来大型强子电子对撞机(LHeC)实验中预期的核PDF约束进行了最新分析。这项新研究是基于一个更灵活的小- $x$参数化,它提供了在该地区,目前没有数据约束的偏差较小的不确定性估计。LHeC的影响通过根据该计划实验的预期精度直接包括伪数据的样本来量化。其结果是,一个显着减少的小$x$不确定性的海夸克和胶子观察。

英文摘要:

An updated analysis regarding the expected nuclear PDF constraints from the future Large Hadron Electron Collider (LHeC) experiment is presented. The new study is based on a more flexible small-$x$ parametrization which provides less biased uncertainty estimates in the region where there are currently no data constraints. The effect of the LHeC is quantified by directly including a sample of pseudodata according to the expected precision of this planned experiment. As a result, a significant reduction of the small-$x$ uncertainties in sea quarks and gluons is observed.
