论文摘要
我们提出了一个su(5)$ \ times $ u(1)$ _ \ text {x} \ times $ u(1)$ _ \ text {pq} $没有susy,因为尚未观察到susy粒子。 $ \ mathrm {u(1)_ {x}} $计对称是$ \ m athrm {u(1)_ {b-l}} $ gauge对称和$ \ mathrm {u(u(1)_ {u(1)_ {pq}} $ symmetry。我们介绍了三个镜像家族,以统一SM量规耦合并避免质子寿命的限制。为了获得羽绒夸克和带电的Leptons的质量差,我们还介绍了$ \ mathbf {45} $表示higgs,除了$ \ mathbf {5} $表示。在本文中,我们讨论了SM和镜子颗粒之间的质量关系,并确定镜子颗粒的质量尺度。由于新粒子以中间能量量表存在,并有助于重新规范化组方程,因此SM量规耦合在高能量下成功地统一。我们的模型可以通过未来的质子衰变搜索来测试,例如,Hyper-Kamiokande实验预期为$τ_p(p \toπ^0 {e^+})<1.0 \ times10^{35} $年。同样,通过使用活性中微子和镜面中微子之间的质量关系,我们估计了重中微子质量的下限。
We propose an SU(5)$\times $U(1)$_\text{X}\times$U(1)$_\text{PQ}$ model without SUSY because the SUSY particles have not been observed yet. The $\mathrm{U(1)_{X}}$ gauge symmetry is the generalization of the $\mathrm{U(1)_{B-L}}$ gauge symmetry and $\mathrm{U(1)_{PQ}}$ symmetry is the global Peccei-Quinn symmetry. We introduce three mirror families in order to unify the SM gauge couplings and avoid the restriction of proton lifetime. In order to obtain the difference of the masses for the down-type quarks and charged leptons, we also introduce the $\mathbf{45}$ representation Higgs in addition to the $\mathbf{5}$ representation one. In this paper, we discuss the mass relations between the SM and mirror particles and identify the mass scales of the mirror particles. Since the new particles exist in the intermediate energy scale and contribute to the renormalization group equation, the SM gauge couplings unify successfully at high energy. Our model can be tested by the future proton decay search, e.g., the Hyper-Kamiokande experiment expected as $τ_p(p\toπ^0{e^+})<1.0\times10^{35}$ years. Also, by using the mass relations between the active and mirror neutrinos, we estimate the lower bound of the heavy neutrino masses.
