Complete UV Resonances of SMEFT Dim-9 Operators for Short-range Neutrinoless Double Beta Decay
Hao-Lin Li, Yu-Han Ni, Ming-Lei Xiao +2
We present a systematic classification of tree-level ultraviolet (UV) completions for dimension-nine SMEFT operators relevant to short-range neutrinoless double beta decay. Using t…

Comprehensive Effective Field Theory Analysis for Baryon Number Violating Processes
Chuan-Qiang Song, Jiang-Hao Yu
Baryon number-violating processes arise generically in many extensions of the Standard Model, with Grand Unified Theories providing the most compelling realizations. Ongoing experi…

On-Shell Renormalization of Dim-8 SMEFT from Complete Amplitude Basis: I. Four-Fermion Operators
Chao Wu, Ming-Lei Xiao, Jiang-Hao Yu +1
We compute the complete one-loop renormalization group equations (RGEs) for all the four-fermion operators at dimension-8 Standard Model Effective Field Theory (SMEFT). We adopt th…
