正电子过剩、发光-暗物质统一和族结构

Positron Excess, Luminous-Dark Matter Unification and Family Structure

Paul H. Frampton, Pham Q. Hung

摘要:

一般认为,暗物质可能由一个或最多几个基本粒子组成。PAMELA的数据提供了一个机会之窗,让我们了解发光物质和暗物质之间可能存在的关系。与ATIC数据一起,这两个正电子过剩被解释为暗物质家族结构的反映。在一个统一的模型中,预测至少第三次增强可能出现在不同的能量。然而,增强的强度取决于族间混合角。

英文摘要:

It is commonly assumed that dark matter may be composed of one or at most a few elementary particles. PAMELA data present a window of opportunity into a possible relationship between luminous and dark matter. Along with ATIC data the two positron excesses are interpreted as a reflection of dark matter family structure. In a unified model it is predicted that at least a third enhancement might show up at a different energy. The strength of the enhancements however depends on interfamily mixing angles.
