论文摘要
惰性ZEE模型是中微子质量的ZEE模型的扩展。这个新模型解释了暗物质的丰度，产生了一个单环中微子质量，并禁止树级希格斯介导的风味变化的中性水流。尽管该模型的暗物质现象学类似于惰性双重模型的暗物质，但新的矢量式费米子的存在将Lepton门户视为新的暗物质歼灭通道。我们研究了这种新门户在低质量制度中的影响，并显示了直接和间接搜索暗物质允许的参数空间。值得注意的是，我们证明了$ M_ {H^0} \ Lessim $ 70 GEV的区域以$λ_l\ Lessim 10^{ - 3} $恢复。我们还表明，LZ和Darwin等未来实验可以测试模型参数空间的大区域。
The inert Zee model is an extension of the Zee model for neutrino masses. This new model explains the dark matter relic abundance, generates a one-loop neutrino masses and forbids tree-level Higgs-mediated flavor changing neutral currents. Although the dark matter phenomenology of the model is similar to that of the inert doublet model, the presence of new vector-like fermions opens the lepton portal as a new dark matter annihilation channel. We study the impact of such a new portal in the low mass regime and show the parameter space allowed by direct and indirect searches of dark matter. Remarkably, we show that the region for $m_{H^0} \lesssim$ 70 GeV is recovered for $λ_L \lesssim 10^{-3}$. We also show that future experiments like LZ and DARWIN could test a large region of the parameter space of the model.
