Title: Renormalization of beta decay at three loops and beyond

Journal Article · · Physical Review. D.

The anomalous dimension for heavy-heavy-light effective theory operators describing nuclear beta decay is computed through three-loop order in the static limit. The result at order Z2⁢a3 corrects a previous result in the literature. An all-orders symmetry is shown to relate the anomalous dimensions at leading and subleading powers of Z at a given order of a. The first unknown coefficient for the anomalous dimension now appears at O⁡(Z2⁢a4).
