Understand

We provide a comprehensive global analysis of Run II top measurements at the LHC in terms of dimension-6 operators.

A distinctive feature of the top sector as compared to the Higgs-electroweak sector is the large number of four-quark operators.
We discuss in detail how they can be tested and how quadratic terms lead to a stable limit on each individual Wilson coefficient.
Predictions for all observables are computed at NLO in QCD.
