论文摘要
我们研究了Dirac质量基质对中微子现象学和宇宙中中微子不对称(BAU)的最大零的预测在一个反seesaw ISS $(2,3)$的框架内的预测。我们试图从$ s_ {4} $风味对称性中找到Dirac Mass Matrix的两个零纹理的起源。 ISS $(2,3)$型号包含两对准迪拉克颗粒和一个在KEV量表中的无菌状态以及三个主动中微子。准迪拉克对的衰减产生了轻子不对称,可以通过Sphaleron过程将其转换为宇宙的重子不对称。因此,可以通过瘦素发生在此框架中解释BAU。我们研究了狄拉克质量矩阵的所有两个零纹理中的BAU。框架内纹理的可行性已通过BAU上的最新宇宙学数据进行了验证。
We study the prediction of maximal zeros of the Dirac mass matrix on neutrino phenomenology and baryon asymmetry of the universe (BAU) within the framework of an inverse seesaw ISS $(2,3)$. We try to find the origin of the allowed two zero textures of the Dirac mass matrix from $S_{4}$ flavor symmetry. ISS $(2,3)$ model contains two pairs of quasi-Dirac particles and one sterile state in the keV scale along with three active neutrinos. The decays of the quasi-Dirac pairs create lepton asymmetry that can be converted to baryon asymmetry of the universe by the sphaleron process. Thus, BAU can be explained in this framework through leptogenesis. We study BAU in all the two zero textures of the Dirac mass matrix. The viabilities of the textures within the framework have been verified with the latest cosmology data on BAU.
