Abstract

A bstract We use dijet measurements from the Large Hadron Collider to constrain ten third-generation four-quark operators in the Standard Model effective field theory. At tree level, only the five operators involving four bottom quarks are directly constrained, but renormalization group (RG) effects allow all ten operators to be probed. Our analysis includes the dominant leading-logarithmic RG contributions up to two-loop order. The resulting bounds for the first five operators are nominal stronger or comparable to current limits, while those for the remaining operators remain weak despite the inclusion of logarithmically enhanced corrections.
