论文摘要
我们表明，由于全球Lepton数字对称性的自发破坏，Modaron是Pseudo-nambu-goldstone玻色子，这可以作为质量范围kev-gev中可行的冻结暗物质的可行冻结，这要归功于较高的dimensional dimensional dimensiality lepton nuble breaking Operator。有趣的是，该提案在标准模型的最简单扩展中受到限制，其中有两个右手中微子和一个单线标量，因此分别解决了轻质中微子质量和自发破坏Lepton数字对称性。所需数量的Maparon生产是从右手中微子的歼灭中进行的，表明中微子物理学与暗物质之间存在着有趣的联系。
We show that Majoron, the pseudo-Nambu-Goldstone boson resulting from the spontaneous breaking of global lepton number symmetry, can present itself as a viable freeze-in type of dark matter in a mass range keV-GeV, thanks to the explicit higher dimensional Lepton number breaking operator. Interestingly, the proposal is restricted within the simplest extension of the Standard Model with two singlet right-handed neutrinos and a singlet scalar so to address light neutrino mass and spontaneous breaking of lepton number symmetry respectively. The desired amount of Majoron production takes place from the annihilations of right-handed neutrinos indicating an intriguing connection between neutrino physics and dark matter.
