论文摘要
四种近代到tribimaximal(NTBM)混合模式被广泛认为是观察到的松性混合结构的可行候选者。随着T2K的最新测量以及密集的全球拟合,$ \sinδ_{cp}> 0 $的间隔在正常顺序中持续很小,而$ \ \sinΔ__{cp} <0 $连续获得$3σ$ $3σ$在内置订单中最高可获得$3σ$。在本文中,我们主张狄拉克CP侵略阶段的拟合结果作为约束,并表明,它基本上可以排除仅从三个混合角度来允许的区域的一半。此外,考虑到小$ \sinδ_{CP}> 0 $间隔,我们发现可以从最新NUFIT 5.1的$3σ$不确定性中选择独特的NTBM模式,当时模式暴露于Yukawa纹理质地胶原性的植物生成,以使Baryon Asmmetry of the Universe的baryon tepention。对于幸存的模式,我们发现Dirac CP侵入阶段与大气角度$θ_{23} $之间的五个$θ_{23}> 45^\ Circ $可以预测$5π/6<δ_{CP} <δ{CP} <π$可以在未来的衡量标准中确认。
Four next-to-tribimaximal (NTBM) mixing patterns are widely considered as the feasible candidates for the observed leptonic mixing structure. With the recent measurements from T2K, as well as intensive global fits, the interval of $\sinδ_{ CP} > 0$ for the Dirac CP-violating phase is persistently small in the normal ordering while $\sinδ_{ CP} < 0$ is successively obtained up to $3σ$ level in the inverted ordering. In this paper, we advocate the fitting results of Dirac CP-violating phase as a constraint, and show that, it can basically rule out half of the regions allowed by the constraint from three mixing angles only. In addition, given the small $\sinδ_{ CP} > 0$ interval, we find that a unique NTBM pattern can be selected out of the four candidates within $3σ$ uncertainty of the latest NuFIT 5.1, when the patterns are exposed to a Yukawa texture-independent leptogenesis for the baryon asymmetry of the Universe. For the surviving pattern, we find an interesting correlation between the Dirac CP-violating phase and the octant of atmospheric angle $θ_{23}$ , where $θ_{23}>45^\circ$ can be predicted once $5π/6 < δ_{CP} <π$ in the normal ordering can be confirmed in the future measurements.
