Description: Analyticity embodies the physical principle of causality. It states that many physical observables can be treated as analytic functions when their parameters take complex values. This seemingly innocuous observation allows for the use of advanced tools from complex analysis, such as dispersion relations, to constrain the possible values that these physical observables may take. Such techniques were first developed for the refractive index in optical systems and quickly adapted by the high-energy physics community. They are nowadays used to constrain S-matrices, decay rates, hadron spectra, and transport coefficients, among others. Recent breakthroughs in these directions call for deeper interactions between subfields which, despite using the same techniques, have largely been disconnected. It is also timely to explore new phenomenological applications, such as constraints on physics beyond the Standard Model, or corrections to Einstein gravity. This workshop, organized jointly between PCTS and IAS, will facilitate establishing new connections by bringing together experts from various theoretical and phenomenological backgrounds to chart the course for future explorations.
