This conference will focus on the interplay between the most recent theoretical developments in the context of QFT, the impact that these can have in guiding and interpreting the result of experimental searches, and the reshaping of the relevant questions that physics BSM must answer. We believe the topic is particularly timely for the following reasons.
First of all, the results produced by the LHC in the past decade challenge the main driving principle for model building BSM: naturalness of the electroweak scale. This principle, realised for instance in models of weak-scale supersymmetry, broadly implies the existence of new particles at energy scales of order the Higgs mass. These particles have not been found at the LHC. This is stimulating more and more creativity in the design of possible scenarios BSM, with unexpected, and partially unexplored, phenomenological consequences.
Moreover, exploration at the LHC is entering a new era (culmination with the extension into the High-Luminosity LHC), where enormous amounts of data are being collected, allowing for a new class of high-energy precision studies. This new measurements are potentially sensitive to new classes of BSM scenarios that received so far little attention because of their elusiveness. Experiments searching for Dark Matter have also been sprouting in recent year, providing an alternative avenue to approach physics BSM.
At the same time, recent years have seen the development of important theoretical tools to improve our understanding of QFTs, especially in the strong coupling regime. The Conformal Boostrap (aimed in particular at conformal field theories, a special class of QFTs), the modern S-matrix bootstrap, as well as modern scattering amplitude techniques, all contribute to refine the map of which QFTs are possible and plausible, and which are not.
Contrary to other conferences and workshops, that tend to focus either on the most theoretical aspects of QFT or on the most practical ones of physics BSM, this conference will aim at studying phenomenologically relevant questions with a more theoretical perspective.
