Abstract
We first discuss the problem of mass hierarchy and review briefly the main Beyond the Standard Model (BSM) proposals. We then describe the framework of strings, branes and large extra dimensions and give the main experimental predictions in both particle accelerators and microgravity experiments testing gravity at short distances. Finally, we present some models based on intersecting branes and discuss the issue of Standard Model embedding.
