暗物质模型选择与ATIC/PPB-BETS异常
Dark Matter Model Selection and the ATIC/PPB-BETS anomaly
摘要：
我们认为，我们可能能够整理出暗物质模型，其中电子产生的湮灭和/或衰变的暗物质，通过使用的事实，即初始能谱反映在宇宙射线的电子通量在地球上观察到，即使在传播通过银河系磁场。为了说明我们的想法，我们集中在三个代表性的初始光谱：（i）单色（ii）平坦和（iii）双峰的。我们发现，这三种情况导致显着不同的能谱，这可能是由费米卫星在运行或即将到来的宇宙射线探测器，如CALET探测。
英文摘要：
We argue that we may be able to sort out dark matter models in which electrons are generated through the annihilation and/or decay of dark matter, by using a fact that the initial energy spectrum is reflected in the cosmic-ray electron flux observed at the Earth even after propagation through the galactic magnetic field. To illustrate our idea we focus on three representative initial spectra: (i)monochromatic (ii)flat and (iii)double-peak ones. We find that those three cases result in significantly different energy spectra, which may be probed by the Fermi satellite in operation or an up-coming cosmic-ray detector such as CALET.
