研究基于部分类\(E_6\)紫外完备模型，通过门户物质场产生轻狄拉克中微子质量，类似司各脱暗物质情景，虽一般类\(E_6\) PM情景在对撞机易探测，但该特定子类直接测试有挑战。
AI 中文摘要
携带标准模型（SM）和暗荷的门户物质（PM）场的圈，可在矢量门户情景中在普通光子和暗光子（DP）之间产生必要的动能混合（KM），从而允许可见和暗区场之间的相互作用。我们表明，基于此类设置的部分类\(E_6\)紫外完备的先前考虑模型的场内容，能在单圈水平产生有趣范围内（约\(0.05\) eV）的轻狄拉克中微子质量，类似于司各脱暗物质（DM）情景。虽然一般类\(E_6\) PM情景已被证明在对撞机（如HL - LHC）上易于探测，但直接独特地测试这些设置的这个特定子类颇具挑战性。
英文摘要
Loops of portal matter (PM) fields, carrying both Standard Model (SM) and dark charges, can generate the necessary kinetic mixing (KM) between the ordinary and dark photons (DP) in vector portal scenarios thus allowing for interactions between visible and dark sector fields. Here we show that the field content of a previously considered model based on a partial $E_6$-like UV-completion of such setups can generate light Dirac neutrino masses in the interesting range, $\sim 0.05$ eV, at the one-loop level similar to what happens in scotogenic dark matter (DM) scenarios. While general $E_6-$like PM scenarios have been shown to be easily probed at colliders, such as the HL-LHC, uniquely testing this specific subclass of these setups in a direct fashion is found to be somewhat more challenging.
