论文摘要
揭开核子内部胶子和夸克的内部动力学是新代碰撞机的研究的主要目标。找到对量子染色体动力学的基本问题的答案，例如核子质量和自旋的起源，在很大程度上取决于我们重建父母黑龙体内的partons 3D运动的能力。我们介绍了提取TMD Parton密度的进步和挑战，特别注意描述胶子极化状态的Parton密度，这仍然代表了一个很大程度上未开发的领域。然后，我们在高能极限，所谓的未集成的gluon分布或UGD中强调了与相应的Parton密度的连接，并且通常与高能物理学的最新发展有关。
Unraveling the inner dynamics of gluons and quarks inside nucleons is a primary target of studies at new-generation colliding machines. Finding an answer to fundamental problems of Quantum ChromoDynamics, such as the origin of nucleon mass and spin, strongly depends on our ability of reconstructing the 3D motion of partons inside the parent hadrons. We present progresses and challenges in the extraction of TMD parton densities, with particular attention to the ones describing polarization states of gluons, which still represent an largely unexplored field. Then, we highlight connections with corresponding parton densities in the high-energy limit, the so-called unintegrated gluon distributions or UGDs and, more in general, to recent developments in high-energy physics.
