  The Standard Model Effective Field Theory (SMEFT) provides a consistent
framework for comparing precision measurements at the LHC to the Standard
Model. The observation of statistically significant non-zero SMEFT coefficients
would correspond to physics beyond the Standard Model (BSM) of some sort. A
more difficult question to answer is what, if any, detailed information about
the nature of the underlying high scale model can be obtained from these
measurements. In this work, we consider the patterns of SMEFT operators present
in five example models and discuss the assumptions inherent in using global
fits to make BSM conclusions. We find that including renormalization group
effects has a significant impact on the interpretation of the results. As a
by-product of our study, we present an up-dated global fit to SMEFT
coefficients in the Warsaw basis including some next-to-leading order QCD
corrections in the SMEFT theory.
