Bouncing cosmology from Kalb-Ramond braneworld

Year: 2008

Type: article

Abstract: We consider a 3-brane embedded in a warped 5-dimensional background with a dilaton and a Kalb-Ramond 2-form. We show that it is possible to find static solutions of the form of the charged dS/AdS-like black hole with horizon which could have a negative mass parameter. The motion of the 3-brane in this bulk generates an effective 4-dimensional bouncing cosmology induced by the negative dark radiation term. This model avoids the instability that arises for the bouncing brane in a Reissner-Nordstr\o{}m-AdS bulk.
