Abstract
It is well known since from the works of D. Glavan and C. Lin [1] that a novel 4D Einstein Gauss-Bonnet (EGB) gravity has be obtained. Here we propose to study EGB black hole in 4D anti-de Sitter (AdS) spacetime, by using entangled states of particles on event horizon and antiparticles on Cauchy horizon. Our reasoning implies that during the disappearance of the black hole singularity, the antimatter also disappear, while the matter are still there, which corresponds to the violation of CP symmetry. We further show that this black hole can be interpreted as a couple of two entangled black holes. The two horizons are connected between them by an ER bridge. We discuss the signatures of charge and anticharge states.
