Extra Dimensions and More

Abstract

One of the most stimulating recent ideas in particle physics involves a possibility that our universe has additional compactified spatial dimensions, perhaps as large as 1 mm. In this review, we discuss the results of recent experimental searches for such large extra dimensions, as well as new developments in this field.
