"Making Perturbative QFT Physical, with Accurate Parton Showers"

In the Standard Model, many features of our the world around us are believed to be a direct consequence of the Higgs sector. The LHC has made amazing progress in exploring this sector, but critical aspects are far from being established. One of the keys to future progress is our ability to accurately simulate collisions across disparate energy scales and to do so in a way that respects essential physical properties such as positivity. To achieve this, we need to learn how to combine the systematic accuracy of QFT with the generality of physical parton showers.
