中微子实验中的光隐费米暗物质

Light Hidden Fermionic Dark Matter in Neutrino Experiments

Jennifer Kile

摘要:

我们认为,在一个模型无关的框架,通过相互作用$\bar{f} p \to e^+ n$,其中$f$是一个暗费米子在中微子探测器中观察暗物质的潜力。运营商的维度6或更少的考虑,和约束被放置在他们的系数使用的暗物质的寿命和它的衰变状态,其中包括$γ$射线或$e^+e^-$对。在这些约束条件下,仍然有一个运营商,可能有助于$\bar{f} p \to e^+ n$在中微子探测器在可观测的水平。然后,我们考虑从Super-Kamiokande遗迹超新星中微子搜索的结果,发现Super-K可以探测这种相互作用的新的物理尺度高达$O(100\mbox{ TeV})$。

英文摘要:

We consider, in a model-independent framework, the potential for observing dark matter in neutrino detectors through the interaction $\bar{f} p \to e^+ n$, where $f$ is a dark fermion. Operators of dimension six or less are considered, and constraints are placed on their coefficients using the dark matter lifetime and its decays to states which include $γ$ rays or $e^+e^-$ pairs. After these constraints are applied, there remains one operator which can possibly contribute to $\bar{f} p \to e^+ n$ in neutrino detectors at an observable level. We then consider the results from the Super-Kamiokande relic supernova neutrino search and find that Super-K can probe the new physics scale of this interaction up to $O(100\mbox{ TeV})$.
