Celestial open strings at one-loop
Laura Donnay, Gaston Giribet, Hernán González +2
We study celestial amplitudes in string theory at one-loop. Celestial amplitudes describe scattering processes of boost eigenstates and relate to amplitudes in the more standard ba…
Celestial IR divergences in general most-subleading-color gluon and gravity amplitudes
Horatiu Nastase, Francisco Rojas, Carlos Rubio
Gluon amplitudes at most-subleading order in the expansion share a remarkable simplicity with graviton amplitudes: collinear divergences are completely absent in both and, as…
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…
Loops on the Celestial Sphere
Hernan A. Gonzalez, Andrea Puhm, Francisco Rojas
We study the effect of loop corrections to conformal correlators on the celestial sphere at null infinity. We first analyze finite one-loop celestial amplitudes in pure Yang-Mills…
Meronic Einstein-Yang-Mills black hole in 5D and gravitational spin from isospin effect
Fabrizio Canfora, Andrés Gomberoff, Seung Hun Oh +2
We construct an analytic black hole solution in Einstein-Yang-Mills theory in five dimensions supporting a Meron field. The gauge field is proportional to a pure gauge and…
Vortices with source, FQHE and nontrivial statistics in 2+1 dimensions
Horatiu Nastase, Francisco Rojas
We investigate vortex soliton solutions in 2+1 dimensional scalar gauge theories, in the presence of source terms in the action. Concretely, this would be applied to anyons, as wel…
