论文摘要
具有OCCAM剃须刀启发的最小I型SEESAW框架，具有Zero Zero Zero-Zero Yukawa和质量矩阵与正常有序的中微子块（目前是数据首选）不相容，而Lepton混合仅起源于中微子部门。此外，通过诱变生成产生观察到的宇宙的巴属不对称所需的最轻的右中音质量（$ M_1 \ sim 10^{14} $ GEV）与Peccei-Quinn的Vanilla场景相抵触，用于Peccei-quinn）axeion axion dark Matter the Universe的宇宙的重新制作的温度在典型的重建温度下，均低于$ 10^^$ 10^^$ 10^^$ 10^^^$ g。在这项工作中，我们提出了一种新的Occam的剃须刀设置，该设置通过包括带电的莱普顿混合以单个角度进行参数化来克服这些问题，该角度预计将非常接近Quark Cabibbo角度。此外，大气混合角位于第二个八分之一中，瘦素发生量表降低至$ \ sim 5.5 \ times 10^{10} $ gev，以斧头暗示的假设提高了张力。
The minimal type-I seesaw framework with texture-zero Yukawa and mass matrices inspired by Occam's razor is incompatible with normally-ordered neutrino masses (currently preferred by data) when lepton mixing originates solely from the neutrino sector. Moreover, the lightest right-handed neutrino mass required to generate the observed baryon asymmetry of the Universe via leptogenesis ($M_1 \sim 10^{14}$ GeV) is in conflict with vanilla scenarios for Peccei-Quinn) axion dark matter where the reheating temperature of the Universe is typically below $10^{12}$ GeV. In this work, we present a new Occam's razor setup which overcomes these problems by including charged-lepton mixing parametrized by a single angle, which is predicted to be very close to the quark Cabibbo angle. Furthermore, the atmospheric mixing angle lies in the second octant and the leptogenesis scale is lowered to $\sim 5.5\times 10^{10}$ GeV, lifting the tension with the axion dark-matter hypothesis.
