论文摘要
我们研究一个可恢复的susy $ so(10)$肠模型,其中Yukawa $ {\ bf 10} $,单$ {\ bf \ overline {\ bf \ overline {126}} $和单$ {\ bf 120} $ fields,$ y_ __ {10} $ {10},y_ _______________________126} Yukawa耦合和中微子质量。 We pursue the possibility that $Y_{10},Y_{126},Y_{120}$ reproduce the correct quark and lepton masses, CKM and PMNS matrices and neutrino mass differences, and at the same time suppress dimension-5 proton decays (proton decays via colored Higgsino exchange) through their texture, so that the soft SUSY breaking scale can be reduced as much as possible没有冲突的质子衰变的当前实验绑定。我们对这种纹理进行数值搜索,并研究该纹理对未知中微子参数的含义,PMNS矩阵的Dirac CP阶段,最轻的中微子质量和$(1,1)$ - 中微质量矩阵的$(1,1)$ - 在带电的Lepton基础上。在这里,我们专注于主要中微子质量主要由2型SEESAW机制生成的情况,在这种情况下,抑制尺寸-5质子衰减与中微子参数的相关性预计最为直接。
We study a renormalizable SUSY $SO(10)$ GUT model where the Yukawa couplings of single ${\bf 10}$, single ${\bf \overline{126}}$ and single ${\bf 120}$ fields, $Y_{10},Y_{126},Y_{120}$, account for the quark and lepton Yukawa couplings and the neutrino mass. We pursue the possibility that $Y_{10},Y_{126},Y_{120}$ reproduce the correct quark and lepton masses, CKM and PMNS matrices and neutrino mass differences, and at the same time suppress dimension-5 proton decays (proton decays via colored Higgsino exchange) through their texture, so that the soft SUSY breaking scale can be reduced as much as possible without conflicting the current experimental bound on proton decays. We perform a numerical search for such a texture, and investigate implications of that texture on unknown neutrino parameters, the Dirac CP phase of PMNS matrix, the lightest neutrino mass and the $(1,1)$-component of the neutrino mass matrix in the charged lepton basis. Here we concentrate on the case when the active neutrino mass is generated mostly by the Type-2 seesaw mechanism, in which case the correlation between the suppression of dimension-5 proton decays and the neutrino parameters is expected to be most direct.
