Abstract
摘要 |
In this talk, I will discuss the geometrization of unitarity constraints for physical observables such as four-point S-matrix for effective field theories (EFT) and correlation functions for CFT. There is a universality that emerges in the resulting geometry which is a reflection of the unification of unitarity, locality and symmetries. On the practical side it allows us to constrain the space of coupling constant for higher dimension operators of EFT, and dimensions as well as OPE coefficients in CFT. |
