Experimental constraints on extra dimensions

In the last few years the proposed existence of large extra dimensions has changed the landscape of high energy physics, suggesting longly sought answers to fundamental questions like the hierarchy problem. To date, several theoretical models have been proposed and a vigorous experimental effort has started, aimed to hunt for manifestations of extra dimensions in form of deviations from the Newton law in short-range tests of gravity or as new particle interactions at the world’s most powerful colliders. An overview is presented of the details of the experimental searches and their findings.
