PAMELA卫星和ATIC气球实验测量到的宇宙射线电子和正电子通量过剩可以解释为暗物质湮灭或衰变成轻子的信号。在本文中，我们表明，再现电子/正电子过剩的暗物质湮灭/衰变可能会从银河系中心产生大量高能中微子。在这种情况下，未来平方公里大小的实验可能会证实这种情况，甚至超级神冈探测器的结果已经对一些暗物质模型施加了限制。
The excess of cosmic ray electron and positron fluxes measured by the PAMELA satellite and ATIC balloon experiments may be interpreted as the signals of the dark matter annihilation or decay into leptons. In this paper, we show that the dark matter annihilation/decay which reproduces the electron/ positron excess may yield a significant amount of high-energy neutrinos from the Galactic center. In that case, future kilometer-square size experiments may confirm such a scenario, or even the Super-Kamiokande results already put constraints on some dark matter models.
