abstract
Over the past years, the interpretation of measurements in the context of effective field theories has attracted much attention in the field of particle physics. We present a tool for interpreting sets of measurements in such models using a Bayesian ansatz by calculating the posterior probabilities of the corresponding free parameters numerically. An example is given, in which top-quark measurements are used to constrain anomalous couplings at the Wtb-vertex.

Probing $t$-channel single top-quark and antiquark production via differential cross-section measurements at $\sqrt{s}=$\SI{13}{\TeV} with the ATLAS detector
Differential cross-sections and their ratio for t-channel single top production are measured at parton level with 140 fb^{-1} of ATLAS data and interpreted in an EFT framework to bound the Wilson coefficient C^{3,1}_{Qq}.
