Constraining Effective Field Theories without Lorentz
IFPU
7-11 July 2025
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 attract- ing 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.
