Description
We review the physics in space times of higher than
4-dimensions with particular emphasis on two extra dimensions. Some recent results
about the spectrum of 3-brane with positive and negative tensions in
gauged supergravities in 6 dimensions will be
discussed. In these theories it is possible to be obtain large mass
gaps even in the large volume limit.
