Abstract

I will explain the Chiral Composite Linear Dilaton (CLD), a novel worldsheet theory recently introduced. It is a beta-gamma system deformed by a linear-dilaton like action made out of a composite of gamma's. I will explain how observables can be computed by a path integral despite high nonlinearity and highlight applications to string duals of chiral 2d Yang-Mills and symmetric product orbifolds and a worldsheet description of a class of generalized Veneziano amplitudes.

Speaker

Dr. Shota Komatsu is currently a scientific staff researcher at the Department of Theoretical Physics of CERN. He received his Ph.D. from the University of Tokyo in 2014 and then worked as a postdoc at Perimeter Institute for Theoretical Physics in Canada (2014 - 2017) and as a postdoc at the Institute for Advanced Study (IAS), Princeton (2017 to 2020). In 2020, he joined the Department of Theoretical Physics of CERN. His fields of interest include Quantum Field Theory, String Theory and integrability.

The seminar will be broadcasted online by Zoom.

Interested people are free to join, without registration in advance.
