Title: S-matrix as a boundary observable
Date (JST): Wed, Aug 30, 2023, 11:00 - 12:00
Place: Seminar Room A
Abstract: In this talk, I will argue that the flat space S-matrix can be computed using the "On-shell Action as a functional of boundary values". In this sense, S-matrix can be thought of as a boundary observable. Next, we analyze constraint given by S-matrix unitarity on the boundary action. Finally I will discuss various properties of this boundary action in position space for both massive and massless particles.
