Fiona Seibold, Scattering on effective strings and compactified membranes 

ITMP seminar, Nov 29, 2023
Speaker: Dr. Fiona Seibold, Imperial College London
Title: Scattering on effective strings and compactified membranes
Abstract: The low-energy dynamics of confining strings is captured by the Nambu-Goto area action, which in critical dimension is related to an integrable TTbar deformation of a free theory. In this talk I will consider the setup of a membrane compactified on a circle, leading to a tower of massive modes. I will present the perturbative worldsheet S-matrix, compare with the Nambu-Goto case, and discuss the integrability of the model.
