在mSUGRA中计算暗物质和中微子质量

Reconciling dark matter and neutrino masses in mSUGRA

Chiara Arina

摘要:

我们研究的情况下,一个替代的跷跷板机制产生中微子质量的最小SUGRA现象。中微子扇区的变化导致超对称粒子谱的改变,而超中微子自然地成为最轻的超对称粒子。所得到的sneutrino具有在WMAP范围内的遗迹密度,并与目前的核反冲边界兼容。

英文摘要:

We study the minimal SUGRA phenomenology in the case of an alternative seesaw mechanism for generating neutrino masses. Changes in the neutrino sector lead to a modification of the supersymmetric particle spectrum and the sneutrino naturally arises as the lightest supersymmetric particle. The obtained sneutrino has a relic density within the WMAP range and is compatible with present nuclear recoil bounds.
