A tale of $Z$+jet: SMEFT effects and the Lam-Tung relation

A tale of $Z$+jet: SMEFT effects and the Lam-Tung relation

We derive constraints on dimension-six light-quark dipole operators within the Standard Model (SM) effective field theory, based on measurements of $Z$ production at SLC and LEP, as well as $Z$+jet production at the LHC. Our new constraints exclude the parameter space that could potentially explain...
