We have developed a framework for automated transverse momentum resummation for arbitrary electroweak final states based on reweighting tree-level events. It is fully differential in the kinematics of the electroweak final states, which facilitates a straightforward analysis of arbitrary observables in the small transverse momentum region. We have implemented the resummation at next-to- next-to-leading logarithmic accuracy and match to next-to- leading fixed-order results using the event generator MadGraph5_aMC@NLO. Results for Z and W boson produc- tion with leptonic decay as well as W Z production are pre- sented. We compare to experimental measurements for the transverse momentum and the angular observable φ∗.
