Two-loop Renormalization Group Equations in the SMEFT
Di Zhang
We calculate two-loop renormalization group equations (RGEs) in the Standard Model Effective Field Theory (SMEFT) with right-handed neutrinos, i.e., the so-called SMEFT, up to d…

Complete Two-loop Renormalization Group Equation of the Weinberg Operator
Alejandro Ibarra, Nicholas Leister, Di Zhang
We calculate the renormalization group equation (RGE) of the lepton-number-violating Weinberg operator with the particle content of the Standard Model (SM), thus completing the set…

Renormalization Group Equations for the Dimension-7 SMEFT Operators
Di Zhang
In this talk, a Green's basis and a new physical basis for dimension-seven (dim-7) operators in the Standard Model effective field theory (SMEFT) are proposed. The reduction relati…
