Description
The Large Hadron Collider (LHC) has entered its fourteenth year of operation. The data collected during the Run I and Run II led to the discovery of the Higgs boson and allowed important precision tests of the Standard Model. On top of that, continuous efforts are being made to search for signals of New Physics up to the energy frontier of few TeV's. Accurate synergy between theoretical predictions and experimental results and comparable precision on both sides is key to foster discoveries, even more so in light of the upcoming High-Luminosity operation of the LHC.
From the theory viewpoint, the path to precision runs through several directions. Computing higher-order corrections to scattering cross sections, modelling realistic final states and estimating the dominant theoretical uncertainties are three important aspects in the process. In this talk I will review recent examples of progress in the latter directions taking the physics case of Top Quark hadroproduction. I will also illustrate current efforts towards the automation of next-to-next-to-leading order computations, with emphasis on two-loop amplitude reduction.
