反常引起的暗物质衰变与PAMELA/ATIC实验

Anomaly Induced Dark Matter Decay and PAMELA/ATIC Experiments

Hiroki Fukuoka, Jisuke Kubo, Daijiro Suematsu

摘要:

PAMELA/ATIC的宇宙射线数据可以用暗物质以$τ_{DM}^{-1}\sim 10^{-26}{sec}^{-1} \sim 10^{-45}{eV}$的衰变率衰变来解释,这是一种在标准模型或其简单的超对称扩展框架内无法理解的能量尺度。我们提出异常诱导的暗物质衰变指数抑制衰变率,并适用于超对称扩展的马的惰性希格斯模型的辐射跷跷板机制的中微子质量。在这个模型中,最轻的右手中微子$ψ_N$和最轻的中性中微子$χ$可以填充观测到的必要的暗物质遗迹,并且发现$ψ_N$可以通过反常衰变为$χ$,衰变率顺序正确,只发射轻子.所有发射的正子都是右旋的。

英文摘要:

The cosmic ray data of PAMELA/ATIC may be explained by dark matter decay with a decay rate $τ_{DM}^{-1}\sim 10^{-26}{sec}^{-1} \sim 10^{-45}{eV}$, an energy scale which could not be understood within the framework of the standard model or its simple supersymmetric extension. We propose anomaly induced dark matter decay to exponentially suppress the decay rate, and apply to a supersymmetric extension of the Ma's inert Higgs model of the radiative seesaw mechanism for neutrino masses. In this model the lightest right-handed neutrino $ψ_N$ and the lightest neutralino $χ$ can fill the observed necessary dark matter relic, and we find that $ψ_N$ can decay into $χ$ through anomaly with a right order of decay rate, emitting only leptons. All the emitted poistrons are right-handed.
