Considering a six-dimensional geometry orbifolded on $S^1/Z_2\times S^1/Z_2$ with quarks and leptons localized on orthogonal branes, we show that the construction admits observable $n-\overline{n}$ oscillation while naturally suppressing the proton decay rates. Consistent with other low-energy observables, the model also accommodates baryogenesis at $\mathcal{O}(10\mathrm{TeV})$ scale.

来自六个维度的中子振荡和重子生成

考虑一个六维几何在${\mathrm{小号}}^1/Z_2\times {\mathrm{小号}}^1/Z_2$夸克和轻子位于正交膜上，我们证明该结构允许可观察到$n-\overline{n}$振荡同时自然地抑制质子衰变率。与其他低能可观测物一致，该模型还适用于$\mathcal{○}(10\mathrm{TeV})$规模。
