大质量的真实的标量粒子，例如来自假定的隐藏扇区的胶球，是有趣的暗物质候选者。如果它们具有排斥性的自我相互作用，可以对抗引力，它们就有可能聚集成大质量的玻色子星。作者表明，相同的排斥性自相互作用也介导了数量变化的湮灭过程，这可能会排除这些恒星在宇宙学相关时间的存在，并排除这些恒星可以提供有趣的引力波签名的参数空间。
Massive real scalar particles, for instance glueballs from a posited hidden sector, are interesting dark matter candidates. If they possess repulsive self interactions that can oppose gravity, they can potentially clump into massive boson stars. The authors show that the same repulsive self interactions also mediate number changing annihilation processes, which may preclude the existence of these stars for cosmologically relevant times and would exclude the parameter space where such stars could provide interesting gravitational wave signatures.
