A FB in the SMEFT: precision Z physics at the LHC
A bstract We study the forward-backward asymmetry A FB in pp → ℓ + ℓ − at the Z peak within the Standard Model Effective Field Theory (SMEFT). We find that this observable provides per mille level constraints on the vertex corrections of the Z boson to quarks, which close a flat direction in the ele...
