论文摘要
我们研究了在未来的成像大气Cherenkov望远镜中，在三环辐射中微子质量生成模型中检测到暗物质中微子质量产生模型（DM）候选模型的前景。我们发现，添加如此大的电动倍数会导致具有$ o（\ text {tev}）$ smos的DM的可观Sommerfeld增强的an灭，并进入SM量规玻色子中，从而导致连续性和线条样光谱具有很高的能量（VHE）伽马射线，因此可以观察到CTA的CTA。我们通过设置$ su（2）_ {l} $ isospin的上限来确定可行的模型，从部分波单位性约束和量规耦合中低规模Landau极的出现。之后，通过考虑从银河中心的DM歼灭产生的连续脉冲射线，我们使用CTA的灵敏度范围探测了模型的参数空间。
We investigate the prospect of detecting the Dark Matter (DM) candidate in the three-loop radiative neutrino mass generation model extended with large electroweak multiplets of the Standard Model (SM) gauge group, at the future imaging atmospheric Cherenkov telescope known as the Cherenkov Telescope Array (CTA). We find that the addition of such large electroweak multiplets leads to a sizable Sommerfeld enhanced annihilation of the DM with $O(\text{TeV})$ mass, into the SM gauge bosons which results in continuum and line-like spectra of very high energy (VHE) gamma-rays, and therefore becomes observable for the CTA. We determine the viable models by setting the upper limit on the $SU(2)_{L}$ isospin of the multiplets from the partial-wave unitarity constraints and the appearance of low-scale Landau pole in the gauge coupling. Afterwards, by considering the continuum VHE gamma-rays produced from the DM annihilation at the Galactic center, we probe the parameter space of the model using the sensitivity reach of the CTA.
