标题： Indirect Detection of a Light Higgsino Motivated by Collider Data

摘要： 卡恩和威尔斯最近提出，对撞机数据表明最轻的超对称伙伴具有类似希格斯ino的性质，这可以解释我们银河晕中的暗物质。他们讨论了在实验室探测器中直接检测这种暗物质粒子的可能性。 在这里，我们提出，如果这种粒子确实是暗物质，那么它可能在另一种实验中被探测到，这些实验旨在寻找来自太阳内部暗物质湮灭产生的高能中微子。我们提供了准确的解析估计，考虑到了所有相关的物理效应。 目前，预测的信号强度大致比实验限制低一到三个数量级，这取决于粒子的质量和耦合；然而，像MACRO、超级神冈探测器和AMANDA这样的探测器将继续收集数据，并在未来五年内能够排除或确认这种暗物质粒子可能的质量范围内的有趣部分。 显示英文摘要

摘要： Kane and Wells recently argued that collider data point to a Higgsino-like lightest supersymmetric partner which would explain the dark matter in our Galactic halo. They discuss direct detection of such dark-matter particles in laboratory detectors. Here, we argue that such a particle, if it is indeed the dark matter, might alternatively be accessible in experiments which search for energetic neutrinos from dark-matter annihilation in the Sun. We provide accurate analytic estimates for the rates which take into account all relevant physical effects. Currently, the predicted signal falls roughly one to three orders of magnitude below experimental bounds, depending on the mass and coupling of the particle; however, detectors such as MACRO, super-Kamiokande, and AMANDA will continue to take data and should be able to rule out or confirm an interesting portion of the possible mass range for such a dark-matter particle within the next five years.
