Title:  On Relations Between Conformal Gravity and Heterotic Strings

Abstract:  In this talk I will discuss basic properties of scattering amplitudes in two seemingly unrelated theories: conformal gravity and heterotic strings. It turns out that they can be studied in a common framework that involve the BCJ double copy and higher-derivative gauge theories. This significantly simplifies the construction of the amplitudes, and it gives new physical insight to these theories that would perhaps otherwise remain hidden behind impenetrable complexity of their standard formulations.
