改进的双大中微子混合与Gatto-Sartori-Tonin类关系

Revamped Bi-Large neutrino mixing with Gatto-Sartori-Tonin like relation

Subhankar Roy, K. Sashikanta Singh, Jyotirmoi Borah

摘要:

Gatto Sartori Tonin(GST)关系建立了以夸克质量比$θ_{C}=\sqrt{m_d/m_s}$表示的Cabibbo角,并将其定义为$θ_{13}=\sqrt{m_1/m_3}$,建立了一个基于混合参数$θ_{13}=θ_{C}$和$θ_{12}=θ_{23}$统一的双大激发轻子混合框架。这种修改除了排除了$θ_{13}$消失的可能性外,还提倡最低中微子质量不为零,并强调了中微子质量的正常顺序。该框架进一步增强了列入一个带电的轻子对角化矩阵$U_{lL}$与$ (θ_{12}^l \sim θ_C, δ=0)$。以大统一理论(GUT)尺度构建的模型进一步向下延伸到$Z$玻色子尺度,以了解GST关系和卡比博角的普遍性。

英文摘要:

The Gatto Sartori Tonin (GST) relation which establishes the Cabibbo angle in terms of the quark mass ratio: $θ_{C}=\sqrt{m_d/m_s}$, is instituted as $θ_{13}=\sqrt{m_1/m_3}$ to a Bi-large motivated lepton mixing framework that relies on the unification of mixing parameters: $θ_{13}=θ_{C}$ and $θ_{12}=θ_{23}$. This modification in addition to ruling out the possibility of vanishing $θ_{13}$, advocates for a nonzero lowest neutrino mass and underlines the normal ordering of the neutrino masses. The framework is further enhanced by the inclusion of a charged lepton diagonalizing matrix $U_{lL}$ with $ (θ_{12}^l \sim θ_C, δ=0)$. The model being architected at the Grand unification theory (GUT) scale is further run down upto the $Z$ boson scale to understand the universality of the GST relation and the Cabibbo angle.
