根据最近的IceCube结果对太阳中Kaluza-Klein暗物质湮灭的限制
Limits on Kaluza-Klein dark matter annihilation in the Sun from recent IceCube results
摘要：
我们解释最近冰立方搜索暗物质积累在太阳中的最轻的卡鲁扎-克莱因激发（假设在这里是卡鲁扎-克莱因光子，$B^1$），获得改进的限制在太阳中的湮灭率，由此产生的中微子通量在地球上和$B^1$ -质子横截面，为$B^1$质量范围为30- 3000 GeV。这些结果提高了以前的结果从冰立方在其22串配置的数量级，取决于质量，但也扩展到$B^1$群众低至30 GeV的结果。
英文摘要：
We interpret recent IceCube results on searches for dark matter accumulated in the sun in terms of the lightest Kaluza-Klein excitation (assumed here to be the Kaluza-Klein photon, $B^1$), obtaining improved limits on the annihilation rate in the Sun, the resulting neutrino flux at the Earth and on the $B^1$-proton cross-sections, for $B^1$ masses in the range 30--3000 GeV. These results improve previous results from IceCube in its 22-string configuration by up to an order of magnitude, depending on mass, but also extend the results to $B^1$ masses as low as 30 GeV.
