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…

Complete UV Resonances of the Dimension-8 SMEFT Operators
Hao-Lin Li, Yu-Han Ni, Ming-Lei Xiao +1
The effective field theory approach parameterizes the low energy behaviors of all possible ultraviolet (UV) theories in a systematic way. One of the most important tasks is thus to…
