We give a brief summary of present bounds on the size of possible extra-dimensions as well as the string scale from collider experiments.
The rate at which cross sections grow with energy is sensitive to the presence of extra dimensions in a rather model-independent fashion. We examine how rates would be expected to grow if there are more spatial dimensions than 3 which…
