Abstract

The Standard Model Effective Field Theory (SMEFT) provides a consistent formalism to parametrise the effects of heavy new physics appearing as deviations from SM expectations. On of the key goals of the LHC legacy will be to cover this parameter space as much as possible and contribute to a global fit of the EFT parameter space and, hopefully, provide hints on the nature of physics beyond the SM. To this end, precise predictions for all observables of interest in the SMEFT are required, both at fixed order and for Monte Carlo event generators interfaced with parton showers. I will present recent developments in this direction, focusing on electroweak Higgs production mechanisms and relevant dimension-6 operators as well as several processes connection Higgs, electroweak and top physics, both at next-to-leading order in QCD . The issue of EFT validity will be discussed alongside some LHC sensitivity studies. We provide a public model implementation that can be interfaced with existing Monte Carlo event generators including a complete (non 4-fermion) set of flavor symmetric operators obeying minimal flavor violation.
