Axions in Gauge Mediation

Linda M. Carpenter, Michael Dine, Guido Festuccia, Lorenzo Ubaldi

摘要:

在超对称理论中,轴子的存在通常意味着非紧的(伪)模空间的存在。在规范介导模型中,轴子似乎是一个特别有希望的暗物质候选者。模的宇宙学约束了引力子质量和轴子衰变常数;前者不能远低于10 MeV,后者不能远大于10^{13} GeV。Axinos,当可识别时,通常很重,在宇宙学中不起重要作用。

英文摘要:

In supersymmetric theories, the presence of axions usually implies the existence of a non-compact, (pseudo)moduli space. In gauge mediated models, the axion would seem a particularly promising dark matter candidate. The cosmology of the moduli then constrains the gravitino mass and the axion decay constant; the former can't be much below 10 MeV; the latter can't be much larger than 10^{13} GeV. Axinos, when identifiable, are typically heavy and do not play an important role in cosmology.
