The present proposal aims at providing new theoretical and phenomenological studies of various hard processes in QCD, with a focus on the importance of hard probes for exploring the inner structure of the nucleon. Our proposal addresses diverse facets, ranging from state-of-the-art perturbative calculations of QCD hard-scattering cross sections, to conceptual progress on the interplay of QCD radiation and parton distributions, and to phenomenological extractions of parton distributions from experimental data. Besides being closely connected scientifically, the various components of our proposed research have in common that they are all of much relevance for ongoing or planned experimental activities of the field.

本文的目的是对QCD中的各种硬过程提供新的理论和唯象研究，重点是硬探针对探索核子内部结构的重要性。我们的建议涉及不同的方面，从国家的最先进的微扰计算QCD硬散射截面，概念上的进展QCD辐射和部分子分布的相互作用，并从实验数据的部分子分布的唯象提取。除了在科学上密切相关外，我们提出的研究的各个组成部分都有一个共同点，即它们都与该领域正在进行或计划进行的实验活动非常相关。
