暗物质正在衰变

Dark Matter Decaying Now

Jose A. R. Cembranos, Jonathan L. Feng, Louis E. Strigari

摘要:

暗物质的不稳定性可能会在宇宙伽马射线的光谱中产生可见的信号。我们认为这种可能性的框架中,额外的空间维度和超对称性。粒子的例子包括超弱相互作用的大质量粒子,如超对称模型中的引力子,具有普遍额外维度的模型中最轻的卡鲁扎-克莱因(KK)态,以及弱相互作用的大质量粒子,如柔性膜世界中的branon。

英文摘要:

The instability of dark matter may produce visible signals in the spectrum of cosmic gamma-rays. We consider this possibility in frameworks with additional spatial dimensions and supersymmetry. Examples of particles include superweakly-interacting massive particles such as gravitinos in supersymmetry models, the lightest Kaluza-Klein (KK) state in models with universal extra dimensions, and weakly-interacting massive particles such as branons in flexible brane-worlds.
