衰变引力子暗物质的Cosmic Ray特征

Cosmic Ray Signatures from Decaying Gravitino Dark Matter

N. -E. Bomark, S. Lola, P. Osland, A. R. Raklev

摘要:

研究了三线性R宇称破坏超对称情形下引力子暗物质慢衰变产生的带电宇宙射线。结果表明,LLE型算子可以很好地解释PAMELA,ATIC和Fermi LAT报道的宇宙线电子和正电子数据中最近的异常,而不违反任何其他界限。这一设想将很快通过费米LAT的扩散伽马射线发射数据进行检验。

英文摘要:

We study the charged cosmic rays arising from the slow decay of gravitino dark matter within supersymmetric scenarios with trilinear R-parity violation. It is shown that operators of the LLE type can very well account for the recent anomalies in cosmic ray electron and positron data reported by PAMELA, ATIC and Fermi LAT, without violating any other bounds. This scenario will soon be tested by the Fermi LAT data on diffuse gamma ray emission.
