Abstract

A bstract We investigate how the interference of the SM with ten four-light quark operators in the SMEFT can be constrained thanks to multijet and Z , W , γ VBF production in association with jets. The differential distributions for each process are generated at LO for different jet multiplicities, that are then merged and showered. We check which observables provide better bounds on the Wilson coefficients, and what directions in the ten-dimensional coefficient space they are able to probe. We discuss the relevance of the quadratic contributions with respect to the linear terms and use them to assess the validity of the EFT approach.
