Abstract

Considering a six-dimensional geometry orbifolded on S1/Z2×S1/Z2 with quarks and leptons localized on orthogonal branes, we show that the construction admits observable n−n¯ oscillation while naturally suppressing the proton decay rates. Consistent with other low-energy observables, the model also accommodates baryogenesis at O(10  TeV) scale.
