The effects of running gravitational coupling on three dimensional black holes

Autor: Rincon, Angel, Koch, Benjamin, Laporte, Cristobal, Canales, Felipe, Cruz, Norman

In the present work, we investigate the consequences of running gravitational coupling on the properties of the three-dimensional BTZ black hole. We take as starting point the functional form of gravitational coupling obtained in the context of asymp

Gauge boson masses from the scale-dependent interplay between the gravitational and the electroweak sector

Autor: Laporte, Cristobal, Koch, Benjamin, Canales, Felipe, Rincon, Angel

In this paper we explore the interplay of scale dependence arising in the electroweak and the gravitational sector. Using the method of variational parameter setting leads naturally to spontaneous symmetry breaking and thus to electroweak gauge boson

Statefinder analysis of scale-dependent cosmology

Autor: Alvarez, Pedro D., Koch, Benjamin, Laporte, Cristobal, Canales, Felipe, Rincon, Angel

We study the statefinder parameters of a cosmological model based on scale-dependent gravity. The effective Einstein field equations come from an average effective action. From the dynamical system, we derive analytical expressions that improve the c

Cosmological constant problem: deflation during inflation

Autor: Canales, Felipe, Koch, Benjamin, Laporte, Cristobal, Rincon, Angel

We argue that the discrepancy between the Planck mass scale and the observed value of the cosmological constant can be largely attenuated if those quantities are understood as a result of effective, and thus scale-dependent, couplings. We exemplify t
