The complex null string, Galilean conformal algebra and scattering equations
Eduardo Casali, Yannick Herfray, Piotr Tourkine
The scattering equation formalism for scattering amplitudes, and its stringy incarnation, the ambitwistor string, remains a mysterious construction. In this paper, we pursue the st…

Topological field theories of 2- and 3-forms in six dimensions
Yannick Herfray, Kirill Krasnov
We consider several diffeomorphism invariant field theories of 2- and 3-forms in six dimensions. They all share the same kinetic term , but differ in the potential term that i…

New first order Lagrangian for General Relativity
Yannick Herfray, Kirill Krasnov
We describe a new BF-type first-order in derivatives Lagrangian for General Relativity. The Lagrangian depends on a connection field as well as a Lie-algebra valued two-form field,…
