Abstract
A comprehensive set of measurements of top quark pair production in association with electroweak bosons (W, Z or $\gamma$) is presented at different centre-of-mass energies. The results are compared to theoretical predictions and re-interpreted as searches for new physics that induce deviations from the standard model expectations using an effective field theory approach. The status of the search for double-tt pair production combining different final states is also reported.
