太阳中NMSSM中性伴子的湮灭和中微子望远镜极限

Annihilation of NMSSM neutralinos in the Sun and neutrino telescope limits

Sergei Demidov, Olga Suvorova

摘要:

我们在NMSSM的框架下研究了中性伴子暗物质,对其参数空间进行了扫描,并计算了中性伴子在太阳中的俘获和湮灭率。根据中性伴子含量及其主要湮灭通道,讨论了在中微子实验中寻找中性伴子暗物质的前景。我们直接从中微子望远镜的太阳湮灭率上限重新计算了中性子-质子弹性截面的上限。该方法与μ子通量极限下的重算方法相比,具有不依赖于实验细节、重算系数对各种WIMP暗物质模型具有通用性等优点。我们得到90%的c.l.根据Baksan地下闪烁望远镜的结果得出的中性子质子截面的上限。

英文摘要:

We investigate neutralino dark matter in the framework of NMSSM performing a scan over its parameter space and calculating neutralino capture and annihilation rates in the Sun. We discuss the prospects of searches for neutralino dark matter in neutrino experiments depending on neutralino content and its main annihilation channel. We recalculate the upper limits on neutralino-proton elastic cross sections directly from neutrino telescopes upper bounds on annihilation rates in the Sun. This procedure has advantages as compared with corresponding recalcalations from the limits on muon flux, namely, it is independent on details of the experiment and the recalculation coefficients are universal for any kind of WIMP dark matter models. We derive 90% c.l. upper limits on neutralino-proton cross sections from the results of the Baksan Underground Scintillator Telescope.
