Abstract

Vortex states of photons, electrons, and other particles are non-plane-wave solutions of the corresponding wave equation with helicoidal wave fronts. These states possess an intrinsic orbital angular momentum with respect to the average propagation direction, which represents a new degree of freedom, previously unexplored in particle or nuclear collisions. Vortex states of photons, electrons, neutrons, and neutral atoms have been experimentally produced, albeit at low energies, and are being intensively explored. Anticipating future experimental progress, one can ask what additional insights on nuclei and particles one can gain once collisions of high-energy vortex states become possible. This review describes the present-day landscape of physics opportunities, experimental progress and suggestions relevant to vortex states in high energy collisions. The aim is to familiarize the community with this emergent cross-disciplinary topic and to provide a sufficiently complete literature coverage, highlighting some results and calculational techniques.

高能涡旋态碰撞的前景与挑战

光子、电子和其他粒子的涡旋态是具有螺旋波前的相应波动方程的非平面波解。这些态具有相对于平均传播方向的固有轨道角动量，这代表了一种新的自由度，以前未在粒子或核碰撞中探索过。光子、电子、中子和中性原子的漩涡态已经在实验中产生，尽管能量很低，并且正在被深入探索。展望未来的实验进展，人们可以问，一旦高能涡旋态的碰撞成为可能，人们可以获得什么关于原子核和粒子的额外见解。本文综述了高能碰撞中涡旋态的物理学机遇、实验进展和相关建议。目的是使社区熟悉这个新兴的跨学科主题，并提供足够完整的文献覆盖，突出一些结果和计算技术。

期刊介绍： Taking the format of four issues per year, the journal Progress in Particle and Nuclear Physics aims to discuss new developments in the field at a level suitable for the general nuclear and particle physicist and, in greater technical depth, to explore the most important advances in these areas. Most of the articles will be in one of the fields of nuclear physics, hadron physics, heavy ion physics, particle physics, as well as astrophysics and cosmology. A particular effort is made to treat topics of an interface type for which both particle and nuclear physics are important. Related topics such as detector physics, accelerator physics or the application of nuclear physics in the medical and archaeological fields will also be treated from time to time.
