摘要：

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 T-2/Z(2) orbifold, a discrete subgroup of the six-dimensional Lorentz group continues to forbid dangerous operators.
