费米子衰变暗物质的ATIC/PAMELA异常

ATIC/PAMELA anomaly from fermionic decaying Dark Matter

Chuan-Hung Chen, Chao-Qiang Geng, Dmitry V. Zhuridov

摘要:

我们证明了一个经济的双Higgs二重态模型可以用暗物质(DM)费米子的三体衰变来解释最近ATIC和PAMELA实验中的电子和正电子过剩现象,而不需要对耦合和质量简并进行微调.我们还表明,衰变DM粒子的质量和寿命可能不会分别固定在1 TeV和10^{26}秒左右。此外,我们注意到,这个模型包括一个稳定的暗物质候选人以及。

英文摘要:

We demonstrate that an economical two Higgs doublet model can explain the electron and positron excesses in the recent ATIC and PAMELA experiments by the three body decays of the dark matter (DM) fermions without requiring the fine turning of the couplings and degeneracy of masses. We also show that the mass and lifetime of the decaying DM particle may not be fixed to be around 1 TeV and 10^{26} sec, respectively. Moreover, we note that this model includes a stable dark matter candidate as well.
