摘要

方位调制对于各种广义粒子分布的现象学提取和分离至关重要。我们提供了一种新的框架选择和相应的形式主义来描述方位角分布，其基础是在不同动量尺度上发生的物理学分离。我们证明，这种新的描述不仅非常适合实验分析，而且在分离不同子过程对同一物理截面的贡献方面也很有优势。

Azimuthal modulations and extraction of generalized parton distributions

Azimuthal modulations are crucial for the phenomenological extraction and separation of various generalized parton distributions. We provide a new choice of frame and corresponding formalism to describe the azimuthal distributions, based on the separation of physics occurring at different momentum scales. We demonstrate that this new description is not only well-suited for experimental analysis, but also advantageous in separating contributions from different subprocesses to the same physical cross section.
