The recent discovery of the Higgs boson at the Large Hadron Collider (LHC) is an event of extraordinary significance, which opened the door to the direct experimental investigation of electroweak symmetry breaking, a mechanism that shapes fundamental aspects of the physical world since the early universe.In the next two decades, the LHC will test the interactions of the Higgs boson with matter and force-carrier particles through a vast campaign of precise measurements, and will explore a new energy range with high discovery potential. In this context, theoretical simulations of particle collisions based on quantum-field theory play a central role for the sensitivity to new phenomena and for the possibility to perform precision tests.The high-energy phase of the LHC experiment poses unprecedented requirements in terms of precision, flexibility and speed of the theoretical simulations. To meet these challenges, in this project we will develop and implement new algorithmic approaches that can advance perturbative simulation techniques beyond the present technical frontiers. The key idea is to merge the OpenLoops method - a powerful approach that was recently introduced by the PI - with new promising ideas that are emerging in the context of algebraic geometry.At next-to-leading order (NLO) in perturbation theory, the new method will open the door to multi-particle calculations for any process with up to seven particles, while the physical content of the simulations will be enhanced by including electroweak quantum effects. Moreover, on the wave of a recent NLO revolution, the proposed approach will automate central aspects of next-to-next-to leading order (NNLO) calculations.These new algorithms will be made publicly available, interfaced to multi-purpose Monte Carlo programs, and applied to a broad range of phenomenological studies at the LHC. Thanks to their high flexibility, they will be widely applicable to the analysis of LHC data, and the resulting gain in precision will greatly enhance the opportunities to challenge the Standard Model at the LHC, both through precision tests and new-physics searches.
