The search for new interactions at the LHC: the top-quark window

New Physics searches at the LHC are mostly being performed with the aim of detecting new states. A complementary strategy is to look for new interactions, something that typically involves precise measurements. In this talk I argue how many of the current SM (and BSM) measurements in the top sector could be used to efficiently and consistently determine of the couplings of an effective field theory and in particular that of the SM at dimension 6.
