This project aims to advance fundamental understanding of collisions involving antimatter. The dominance of matter over antimatter in the Universe is one of the most intriguing questions of today’s science. Researchers at the European Organisation for Nuclear Research (CERN) are addressing this question by creating antihydrogen and studying its properties, including the gravitational behaviour. By trapping and cooling antihydrogen positive ions, ultra-cold antihydrogen atoms can be created and used in free fall experiments at CERN. The convergent close-coupling method and threshold theory will be used to provide the necessary theoretical guidance for the experimental antihydrogen positive ion formation via low-energy positronium-antiproton and positronium-antihydrogen collisions.

该项目旨在促进对涉及反物质的碰撞的基本理解。宇宙中物质对反物质的主导地位是当今科学中最有趣的问题之一。欧洲核子研究组织（CERN）的研究人员正在通过创造反氢并研究其性质（包括引力行为）来解决这个问题。通过捕获和冷却反氢正离子，超冷反氢原子可以被创造出来，并用于欧洲核子研究中心的自由落体实验。收敛紧耦合方法和阈值理论将为低能正电子素-反质子和正电子素-反氢碰撞形成反氢正离子的实验提供必要的理论指导。
