Physics of Extra Dimensions as IR Limit of Four-Dimensional Theories
Abstract
Description
I discuss the recent work done in collaboration with Chris Hill, Jing Wang and Hsin-Chia Cheng. We construct four-dimensional renormalizable gauge theories which, in their infrared limit, generate the dynamics of gauge interactions in flat extra dimensions. In this construction, the Kaluza-Klein states of extra dimensions arise from having many gauge symmetries in four dimensions. The IR limit is determined by the dynamics of spontaneous breakdown of those symmetries.
