A new dynamic is identified between dark matter and nuclei. Nuclei accelerated to MeV energies by the internal potential of composite dark matter can undergo nuclear fusion. This effect arises in simple models of composite dark matter made of heavy fermions bound by a light scalar field. Cosmologies and detection prospects are explored for composites that catalyze nuclear reactions in underground detectors and stars, including bremsstrahlung radiation from nuclei scattering against electrons in hot plasma formed in the composite interior. If discovered and collected, this kind of composite dark matter could in principle serve as a ready-made, compact nuclear fusion generator.

暗物质内部的核聚变

在暗物质和原子核之间发现了一种新的动力学。由复合暗物质的内部势能加速到 MeV 能量的原子核可以进行核聚变。这种效应出现在由轻标量场束缚的重费米子组成的复合暗物质的简单模型中。探索了在地下探测器和恒星中催化核反应的复合材料的宇宙学和探测前景，包括来自核散射对复合材料内部形成的热等离子体中的电子的轫致辐射。如果被发现和收集，这种复合暗物质原则上可以作为现成的、紧凑的核聚变发生器。
