中微子扇区和冷暗物质的模型构造

Model Bulding for the Neutrino Sector and Cold Dark Matter

Hiroshi Okada

摘要:

现在已经很清楚,中微子区的质量要比其他三个区的质量轻得多。有很多人试图用惰性希格斯玻色子来解释中微子的辐射质量,希格斯玻色子没有真空期望值。然后我们可以讨论冷暗物质候选者,因为不需要如此重的粒子,并且具有对应于MSSM的R宇称对称性的$Z_2$宇称对称性。最著名的作品是Zee模型。最近,E. MA.我们引入了一种基于二面体群$D_6$的味对称性来约束汤川扇区。对于中微子部分,我们发现大气中微子的混合达到了最大值,并且只有一个倒置的质量谱,$|V_{MNS_{13}}|$的值为0.0034等等.对于费米子CDM候选者,我们发现CDM和惰性Higgs的质量应该分别大于230和300 GeV.如果我们把自己限制在微扰区,它们应该比750 GeV轻。

英文摘要:

It is now clear that the masses of the neutrino sector are much lighter than those of the other three sectors.There are many attempts to explain the neutrino masses radiatively by means of inert Higgses, which don't have vacuum expectation values. Then one can discuss cold dark matter candidates, because of no needing so heavy particles and having a $Z_2$ parity symmetry corresponding to the R-parity symmetry of the MSSM. The most famous work would be the Zee model. Recently a new type model along this line of thought was proposed by E. Ma. We introduce a flavor symmetry based on a dihedral group $D_6$ to constrain the Yukawa sector. For the neutrino sector, we find that the maximal mixing of atmospheric neutrinos is realized, it can also be shown that only an inverted mass spectrum, the value of $|V_{MNS_{13}}|$ is 0.0034 and so on. For the fermionic CDM candidates, we find that the mass of the CDM and the inert Higgs should be larger than about 230 and 300 GeV, respectively. If we restrict ourselves to a perturbative regime, they should be lighter than about 750 GeV.
