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 2017 May 20 stellar occultation by the elongated centaur (95626) 2002 GZ
P. Santos-Sanz, J. L. Ortiz, B. Sicardy +56
We predicted a stellar occultation of the bright star Gaia DR1 4332852996360346368 (UCAC4 385-75921) (m= 14.0 mag) by the centaur 2002 GZ for 2017 May 20$^{\rm th}…
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…
Classical Planck Spectrum for Relative Thermal Radiation, Classical Zero-Point Radiation, and Scale Parameter
J. Tapia, H. González, R. Rubiano
In this work we obtain Planck's blackbody spectrum from the thermal scalar radiation contained in a resonant cavity of volume V in the context of classical mechanics, which provide…
Magnetostatic Analogy of the Zero Energy State of Jackiw-Rebbi
R. Rubiano
We prepared a similarity between the Poisson equation in non-homogeneous magnetic material media and Dirac's one-dimensional equation for the zero-energy state, which establishes a…
A 2D field theory equivalent to 3D gravity with no cosmological constant
Glenn Barnich, Andrés Gomberoff, Hernán A. González
In (2+1) space-time dimensions the Einstein theory of gravity has no local degrees of freedom. In fact, in the presence of a negative cosmological term, it is described by a (1+1)…
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…
The flat limit of three dimensional asymptotically anti-de Sitter spacetimes
Glenn Barnich, Andrés Gomberoff, Hernán A. González
In order to get a better understanding of holographic properties of gravitational theories with a vanishing cosmological constant, we analyze in detail the relation between asympto…
Quark mixings as a test of a new symmetry of quark Yukawa couplings
H. González, S. R. Juárez W., P. Kielanowski +1
Based on the hierarchy exhibited by quarks masses at low energies, we assume that Yukawa couplings of up and down quarks are related by at grand unification scal…
