复合信使模型中的衰变暗物质重子

Decaying Dark Matter Baryons in a Composite Messenger Model

Koichi Hamaguchi, Eita Nakamura, Satoshi Shirai, T. T. Yanagida

摘要:

质量为O(100)TeV的重子束缚态,在低标度规范介导下由强相互作用的信使夸克组成,自然可以成为冷暗物质。有趣的是,我们发现这样的重子暗物质一般是亚稳态的,这种暗物质的衰变可以自然地解释PAMELA合作组最近观察到的异常正电子通量。

英文摘要:

A baryonic bound state with a mass of O(100) TeV, which is composed of strongly interacting messenger quarks in the low scale gauge mediation, can naturally be the cold dark matter. Interestingly, we find that such a baryonic dark matter is generically metastable, and the decay of this dark matter can naturally explain the anomalous positron flux recently observed by the PAMELA collaboration.
