Braneworlds and Large Extra Dimensions

The idea of extra dimensions has always played an important rôle in string theory. However, until recently, most of the interest has been on small extra dimensions. With the introduction of braneworlds, this view has been turned around, and many investigations have been made of incorporating large extra dimensions into string theory. Here I provide a brief survey of how such large dimensions may arise from string theory, and additionally discuss some experimental signatures for extra dimensions. © 2003 American Institute of PhysicsPeer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/87317/2/147_1.pd
