TL;DR

This paper investigates charged black hole solutions on a brane within the DGP model, identifying two solution branches that extend known Schwarzschild solutions to include charge effects.

Contribution

It presents new charged black hole solutions on the DGP brane, revealing two distinct solution branches and generalizing previous uncharged models.

Findings

Two types of solutions: regular and accelerated branches.

Solutions reduce to Schwarzschild when charge is zero.

Extension of black hole solutions to include charge in DGP model.

Abstract

We consider charged black holes localized on a three-brane in the DGP model. With a spherically symmetric metric ansatz on the brane and assuming a Z_2-symmetry across the brane, we find two types of solutions which correspond to the so-called regular and accelerated branches in the DGP model. When the charge of the black hole vanishes, our solutions agree with the Schwarzschild solutions obtained by Gabadadze and Iglesias.
