Testing Extra Dimensions
Jonathan Feng, University of California, Irvine

The question of how many spatial dimensions there are is among the most tantalizing issues in particle physics and cosmology. In particular, extra dimensions may help explain key features of our world, such as the weakness of gravity and the existence of dark matter. I will discuss these problems, the role of extra dimensions in proposed solutions, and the implications for a wide variety of near future experiments.
