Renormalization of the SMEFT to Dimension Eight: Fermionic Interactions II
Supratim Das Bakshi, Mikael Chala, Zhe Ren
We compute the one-loop mixing of bosonic and two-fermion interactions into two-fermion operators in the dimension-eight Standard Model Effective Field Theory (SMEFT). Together wit…

Positivity from J-Basis Operators in the Standard Model Effective Field Theory
Chengjie Yang, Zhe Ren, Jiang-Hao Yu
In the effective field theory (EFT), the positivity bound on dim-8 effective operators tells us that the contribution in the scattering amplitude of 2-to-2 process geometrica…
