用于在规范调解中检测Q球暗物质的IceCube势

IceCube potential for detecting Q-ball dark matter in gauge mediation

Shinta Kasuya, Masahiro Kawasaki, Tsutomu T. Yanagida

摘要:

我们研究规范介导的超对称破缺中的Q球暗物质,并寻求在冰立方实验中探测的可能性。我们发现Q球是不同于引力子暗物质的暗物质。特别是Q球是一个很好的低再加热温度的暗物质候选者,这可能适合于Affleck-Dine重子生成和/或非热稀薄生成。暗物质Q球可以在未来的IceCube实验中被探测到,这是与引力子暗物质相比的独特之处。

英文摘要:

We study Q-ball dark matter in gauge-mediated supersymmetry breaking, and seek the possibility of detection in the IceCube experiment. We find that the Q balls would be the dark matter in the parameter region different from that for gravitino dark matter. In particular, the Q ball is a good dark matter candidate for low reheating temperature, which may be suitable for the Affleck-Dine baryogenesis and/or nonthermal leptogenesis. Dark matter Q balls are detectable by IceCube-like experiments in the future, which is the peculiar feature compared to the case of gravitino dark matter.
