摘要:

悉尼·科尔曼提出的Q球仍是经典场论中局域化物体形成的一个极具吸引力的实例,其存在独立于量子演化。这类物体可通过Affleck-Dine碎裂等模型在早期宇宙中形成并发生碰撞,也可通过多种机制大量产生,具备不同的尺寸和电荷,成为暗物质候选体,上述理论可能性使得详细研究Q球碰撞现象学十分重要。本研究中,我们利用一套新的、用于耦合引力的标量场的通用代码包,给出了Q球碰撞及其引力波的研究结果,并就未来引力波探测器搜寻Q球碰撞信号的可能性进行了评述。

英文摘要:

Sydney Coleman's Q-ball remains a compelling instance of localised object formation within classical field theory, independently of the quantum evolution. The theoretical possibility of such objects forming and colliding in the early universe from models such as Affleck-Dine fragmentation, or from a number of mechanisms where they are produced copiously with various size and charges to be dark matter candidates, makes it important to study in detail Q-ball collision phenomenology. In this work we present results from a study of Q-ball collisions and their gravitational waves, using a new general code package for scalar fields coupled to gravity. We then comment on the possibility of future gravitational wave detectors searching for signals of Q-ball collisions.
