Mina Ketan Parida, Riyanka Samantaray

摘要:

超对称(SUSY)大统一理论(GUTs)似乎是理解自然界中强、弱和电磁相互作用的最佳动机。我们简要地回顾了新的公式运行费米子质量有效的直接破缺的大统一理论的出现。本文讨论了夸克和中微子混合的高尺度混合统一以及大统一理论预言中理论不确定性消失定理的存在性。指出SO(10)表象的D宇称性质导致了大量的中间破缺模型。根据中微子质量、轻子味破坏、引力子约束下的轻子生成重子生成和质子衰变等理论,给出了超对称SO(10)的统一预言。进一步讨论了在SUSY SO(10)$\times S_4$中通过R宇称和D宇称守恒的左右对称中间破缺实现味统一和拟合所有费米子质量的可能性。在没有超对称性的两个有趣的可能性最小的大沙漠修改,只有一个中间质量标量在每种情况下和它们的应用程序暗物质衰变通过I型跷跷板简要说明。本文简要介绍了非超对称SO(10)中II型跷跷板效应的新解释、新CP不对称公式的出现、解释WIMP暗物质的模型能力、标量势的真空稳定性以及实验观测到的质子寿命极限。

英文摘要:

Supersymmetric (SUSY) grand unified theories (GUTs) appear to be best motivated for understanding strong, weak and electromagnetic interactions of nature. We briefly review emergence of new formulas for running fermion masses valid in direct breaking of GUTs. High scale mixing unification of quark and neutrino mixings and existence of theorems on vanishing theoretical uncertainties in GUT predictions are discussed. D-Parity properties of SO(10) representations leading to large number of intermediate breaking models are pointed out. Unification predictions of SUSY SO(10) in the light of neutrino mass, lepton flavor violation, baryogenesis via leptogenesis within gravitino constraint, and proton decay are noted. We further discuss realisation of flavour unification and possibility of fitting all fermion masses through R-Parity and D-Parity conserving left-right symmetric intermediate breaking in SUSY SO(10)$\times S_4$. In the absence of SUSY two interesting possibilities of minimal grand desert modifications with only one intermediate mass scalar in each case and their applications to dark matter decay through type-I seesaw are briefly noted. Heavy scalar triplet decay leptogenesis through new ansatz for type-II seesaw dominance in non-SUSY SO(10), emergence of new CP asymmetry formulas and model capabilities to explain WIMP dark matter, vacuum stability of the scalar potential and experimentally observed limit on proton lifetime are briefly summarized.
