非超对称SO(10)模型中费米子观测量的运行

Running of Fermion Observables in Non-Supersymmetric SO(10) Models

Tommy Ohlsson, Marcus Pernow

摘要:

我们研究了费米子观测量在两种不同的基于规范群$\textrm{SO}(10)$的非超对称模型中的完全重整化群运行,其中规范群具有中间对称性破缺.与以前的工作结果相反,我们发现,与更小的汤川部门的拉格朗日模型未能再现在电弱尺度的观测值,而与更扩展的汤川部门的模型可以这样做,如果中微子质量有正常的顺序。找到可接受的拟合测量数据的困难是由于中间对称性破缺的影响以及轻子混合角$θ^\ell_{23}$值的张力增加了复杂性。

英文摘要:

We investigate the complete renormalization group running of fermion observables in two different realistic non-supersymmetric models based on the gauge group $\textrm{SO}(10)$ with intermediate symmetry breaking for both normal and inverted neutrino mass orderings. Contrary to results of previous works, we find that the model with the more minimal Yukawa sector of the Lagrangian fails to reproduce the measured values of observables at the electroweak scale, whereas the model with the more extended Yukawa sector can do so if the neutrino masses have normal ordering. The difficulty in finding acceptable fits to measured data is a result of the added complexity from the effect of an intermediate symmetry breaking as well as tension in the value of the leptonic mixing angle $θ^\ell_{23}$.
