In addition to the well-known quantum chromodynamical theta angle, we show that the Standard Model has another theta angle which is invariant under arbitrary chiral rotations of quarks and leptons. The new theta angle coincides with the quantum electrodynamical theta angle, which may be observable in a spacetime with nontrivial topology, either beyond the visible universe or in an effective...
