New physics and SM parameters can be studied and constrained by looking at the modifications to top-pair differential kinematical distributions due to off-shell effects. I present here three case studies: the determination of the Higgs couplings to the top-quark, a search for generic BSM scalar and pseudoscalar states, and a search for Axion Like Particles (ALP). The corresponding models have been implemented in the UFO format to allow automatic computations within MadGraph5_aMC@NLO.
