Description
Proton decay can be sufficiently suppressed in an extra-dimensional model where Standard-Model (SM) fermions are localized at different points in the extra dimension(s), whereas $n$-$\bar n$ oscillations can occur at a rate comparable to the current observable limit. We show that in a left-right symmetric model with extra dimensions this effect is even more enhanced. Several nucleon and dinucleon decays to leptonic final states are considered in the extra-dimensional framework and found to be sufficiently suppressed. $n$-$\bar n$ oscillations are special in this extra-dimensional framework as separating quark and lepton wavefunctions in the extra dimensions to suppress nucleon and dinucleon decays to leptonic final states does not suppress $n$-$\bar n$ oscillations, which only involve quarks.
