The structure of IR divergences in celestial gluon amplitudes
Hernán A. González, Francisco Rojas
The all-loop resummation of SU gauge theory amplitudes is known to factorize into an IR-divergent (soft and collinear) factor and a finite (hard) piece. The divergent factor i…
The anisotropic chiral boson
Oscar Fuentealba, Hernán A. González, Miguel Pino +1
We construct the theory of a chiral boson with anisotropic scaling, characterized by a dynamical exponent , whose action reduces to that of Floreanini and Jackiw in the isotropi…
Three-dimensional Bondi-Metzner-Sachs invariant two-dimensional field theories as the flat limit of Liouville theory
Glenn Barnich, Andrés Gomberoff, Hernán A. González
In the gravitational context, Liouville theory is the two-dimensional conformal field theory that controls the boundary dynamics of asymptotically AdS_3 spacetimes at the classical…
