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…

Threshold Effects on the Massless Neutrino in the Canonical Seesaw Mechanism
Di Zhang
In this work, we revisit the one-loop renormalization group equations (RGEs) among non-degenerate seesaw scales, i.e., threshold effects in the canonical seesaw mechanism, which ha…

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…
