Effective Field Theories (EFTs) are the cornerstone of modern theoretical physics. In the last fifteen years it has been widely appreciated that “not anything goes” in EFTs: fundamental principles such as unitarity and causality place strong constraints on the space of possible theories. The question of how to extend this observation to contexts where Lorentz invariance is spontaneously broken is attracting increased attention. Several approaches have been put forward, each with its own advantages and drawbacks. Time is ripe to bring together experts to share viewpoints and debate recent developments. This workshop will host a diverse group of international researchers, with complementary perspectives and expertise, to discuss open questions and define theoretical targets across different fields, with the ultimate goal of learning what is allowed—and what is not—in our Universe.
Organizers:
Paolo Creminelli (ICTP)
Alessandro Podo (IHES, Bures-sur-Yvette)
Borna Salehian (ETH, Zurich)
This workshop is an IFPU Focus Week, organized at the IFPU institute.
The institute is located next to ICTP, in the Miramare campus at Via Beirut 2, Trieste, Italy. You can find information on how to reach it at this webpage: https://www.ifpu.it/how-to-reach-us/
