Baryon number, lepton number, and operator dimension in the Standard Model
We prove that for a given operator in the Standard Model (SM) with baryon number ΔB and lepton number ΔL, that the operator's dimension is even (odd) if (ΔB−ΔL)/2 is even (odd). Consequently, this establishes the veracity of statements that were long observed or expected to be true, but not pro...
