Abstract

We show that Lorentz and gauge invariance explain the long proton lifetime within the standard model in six dimensions. The baryon-number violating operators have mass dimension 15 or higher. Upon TeV-scale compactification of the two universal extra dimensions on a square T2/Z2T^2/Z_2 orbifold, a discrete subgroup of the 6-dimensional Lorentz group continues to forbid dangerous operators.
