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…

Moments for positivity: using Drell-Yan data to test positivity bounds and reverse-engineer new physics
Xu Li, Ken Mimasu, Kimiko Yamashita +3
Moments of the leptonic angular distribution in the Drell-Yan process have recently been shown to be sensitive probes of a specific class of dimension-8, four-fermion operators in…

Positivity in Multi-Field EFTs
Xu Li, Hao Xu, Chengjie Yang +2
We discuss the general method for obtaining full positivity bounds on multi-field effective field theories (EFTs). While the leading order forward positivity bounds are commonly de…
