Stringent bounds on the brane width from stellar interferometry and distant gamma ray bursts: Back to the hierarchy problem?
Abstract
Description
A simple idea restricting the brane width due to astronomical observations is proposed. Not to contradict the observational data the brane width should be of about Planck size giving therefore strict criterion in selecting the realistic braneworld models.
