TL;DR
This paper uses IceCube data to exclude the remaining parameter space for strongly interacting dark matter particles in a broad mass range, significantly constraining their possible properties.
Contribution
It provides the first comprehensive analysis ruling out the allowed window for strongly interacting dark matter using IceCube data.
Findings
Remaining dark matter window is ruled out.
IceCube's sensitivity covers a broad mass range.
Complete IceCube detector will further improve constraints.
Abstract
We use the recent results on dark matter searches of the 22-string IceCube detector to probe the remaining allowed window for strongly interacting dark matter in the mass range 10^4<m_X<10^15 GeV. We calculate the expected signal in the 22-string IceCube detector from the annihilation ofsuch particles captured in the Sun and compare it to the detected background. As a result, the remaining allowed region in the mass versus cross sectionparameter space is ruled out. We also show the expected sensitivity of the complete IceCube detector with 86 strings.
