This has inspired many model building ideas aimed at solving the hierarchy problem. Most solutions, including supersymmetry and strong dynamics, predict new physics accessible at the TeV scale. Further, these paradigms dictate a specific structure for much of the collider phenomenology at the LHC — top-partners or extended electroweak symmetry breaking scalar sectors are characteristic predictions. On the other hand, there is currently no experimental evidence for new TeV scale physics.
The goal of the workshop is to robustly understand the connection between the hierarchy problem and predictions for new physics derived from its possible solutions. The set of predictions arising from the mechanisms developed so far have been a main driver for theory and experiment. Therefore, sharpening this implication will shape expectations for new physics at the TeV scale. Is new TeV scale physics guaranteed by naturalness? If not, exploring any possible caveats that dilute this correspondence is critical. New mechanisms will have a significant impact on our understanding of quantum field theory. Furthermore, they could uncover profound interplay between gravity and field theory, and possibly connect with the cosmological constant problem.
We aim to bring together experimentalists and theorists to develop a modern understanding of electroweak scale naturalness. Traditional paradigms will be juxtaposed with new ideas for solving the hierarchy problem. Phenomenological implications of naturalness will also be a significant area of attention. The discovery of a light elementary scalar in Nature is a profound fact with far-reaching implications which will guide the future of particle physics.
