Abstract

We present a minimal basis for non-derivative baryon-number-violating operators in the Standard Model Effective Field Theory up to mass dimension 11, as well as for the (ΔB,ΔL)=(2,2)(\Delta B,\Delta L) = (2,2) and (2,2)(2,-2) operators at dimension 12. Compared to existing results, our bases generally contain fewer terms and simpler contractions, although we also highlight select cases where a minimal basis is incompatible with simple structures.
