IceCube,DeepCore,PINGU和超对称暗物质的间接寻找

IceCube, DeepCore, PINGU and the indirect search for supersymmetric dark matter

Paul Bergeron, Stefano Profumo

摘要:

一种可能是最轻的CP-甚至是标准模型(MSSM)最小超对称扩展中的希格斯粒子的发现,以及迄今为止在LHC上缺乏超对称性证据的现象,具有许多深远的影响,包括超对称暗物质的现象学。在这项研究中,我们重新评估并更新了用中微子望远镜探测超对称中性中微子的前景,特别关注IceCube/DeepCore望远镜及其拟议的扩展PINGU。用IceCube探测器MSSM中性暗物质模型以一种重要的方式对来自太阳的高能中微子进行了验证,该模型具有正确的希格斯质量。这是特别是中性伴子暗物质模型产生硬中微子光谱的情况下,在广泛的质量范围内,而PINGU预计将提高检测器的灵敏度,特别是在低中性伴子质量范围内的模型。

英文摘要:

The discovery of a particle that could be the lightest CP-even Higgs of the minimal supersymmetric extension of the Standard Model (MSSM) and the lack of evidence so far for supersymmetry at the LHC have many profound implications, including for the phenomenology of supersymmetric dark matter. In this study, we re-evaluate and give an update on the prospects for detecting supersymmetric neutralinos with neutrino telescopes, focussing in particular on the IceCube/DeepCore Telescope as well as on its proposed extension, PINGU. Searches for high-energy neutrinos from the Sun with IceCube probe MSSM neutralino dark matter models with the correct Higgs mass in a significant way. This is especially the case for neutralino dark matter models producing hard neutrino spectra, across a wide range of masses, while PINGU is anticipated to improve the detector sensitivity especially for models in the low neutralino mass range.
