The Standard Model (SM) of particle physics is the theory that best represents our current knowledge of the fundamental components of matter and their interactions. The discovery of the Higgs boson at the CERNs Large Hadron Collider (LHC) in 2012, 50 years after it was theoretically predicted, represented a major insight in our understanding of the microscopic quantum world and, as the unique elementary scalar particle known, has ushered in an exciting path for research in a new and uncharted territory. Many properties of the Higgs boson are, however, still unknown and have not yet been tested experimentally, such as the couplings to the lightest particles and the strength of its selfinteractions. The complexity of the flavour structure, namely the existence of three families of quarks and leptons and how they transform into each other, remains also a mystery even in the SM. The Higgs boson has also been advocated as the portal to dark matter. Many of the proposed solutions to these enigmas predict the observation of new particles, new forces or extra dimensions of space-time at very high energies. The direct search for new physics at the energy frontier, as now provided by the LHC, is the primary discovery strategy, and a unique opportunity to stress-test the SM in its full breadth. This is complemented by precise flavour measurements at the intensity frontier that are sensitive to new dynamics at higher scales, not yet directly accessible in current colliders.
The purpose of the workshop is to present the most recent advances in theoretical predictions at the LHC and flavour factories, including higher-order perturbative methods, non-perturbative approaches, effective field theories and quantum algorithms.
