人们常说，与典型的弱相互作用大质量粒子相比，不对称暗物质是轻的。在这里，我们指出了一个简单的计划与中微子门户和不对称的暗物质，这可能是“添加”到任何标准的电弱重子生成的情况。暗区包含一个标准模型规范群的副本，以及一个物质家族（至少），希格斯和右手中微子。在重子生成之后，一些轻子的不对称性通过中微子入口转移到暗扇区，在那里暗的球重子将其转化为暗的重子不对称性。暗强子形成不对称的暗物质，并且由于矢量门户可以直接检测到。令人惊讶的是，即使是暗反中子，如果它们具有相当大的电偶极矩，也可以直接检测到。暗光子在当前和未来的实验中明显衰减，这些实验探索了暗物质直接探测搜索的互补参数空间。奇特的希格斯衰变是未来希格斯工厂的极好信号。
It is often said that asymmetric dark matter is light compared to typical weakly interacting massive particles. Here we point out a simple scheme with a neutrino portal andasymmetric dark matter which may be “added” to any standard electroweak baryogenesis scenario. The dark sector contains a copy of the Standard Model gauge group, as well as one matter family (at least), Higgs, and right-handed neutrino. After baryogenesis, some lepton asymmetry is transferred to the dark sector through the neutrino portal where dark sphalerons convert it into a dark baryon asymmetry. Dark hadrons form asymmetric dark matter and may be directly detected due to the vector portal. Surprisingly, even dark anti-neutrons may be directly detected if they have a sizeable electric dipole moment. The dark photons visibly decay in current and future experiments which probe complementary parameter space to dark matter direct detection searches. Exotic Higgs decays are excellent signals at futureHiggs factories.
