It provides a comprehensive overview of models and experimental searches for extra dimensions and black holes, including recent Tevatron results and black hole phenomenology at the LHC.

Findings

Tevatron has set limits on large and Randall-Sundrum extra dimensions.

Potential for copious mini-black hole production at the LHC if quantum gravity scale is around 1 TeV.

Discussion of black hole signatures and phenomenology at colliders.

Abstract

Searches for extra spatial dimensions remain among the most popular new directions in our quest for physics beyond the Standard Model. High-energy collider experiments of the current decade should be able to find an ultimate answer to the question of their existence in a variety of models. We review these models and recent results from the Tevatron on searches for large, inverse-TeV-size, and Randall-Sundrum extra spatial dimensions. The most dramatic consequence of low-scale (~1 TeV) quantum gravity is copious production of mini-black holes at the LHC. We discuss selected topics in the mini-black-hole phenomenology.
