``Limits on the Size of Extra Dimensions''

One of the most concrete and startling predictions of string theory is the existence of at least six additional spatial dimensions. If these extra dimensions are large enough, they would produce unmistakeable signatures in high-energy particle collisions, such as the production of microscopic black holes. I will discuss the generic phenomenology of extra dimensions, current experimental limits on their size, and prospects for improving these limits in coming years.

Refreshments will be served in CP 155 at 3:15 PM
