ar X iv : h ep - p h / 01 11 02 7 v 1 2 N ov 2 00 1 Models with Extra Dimensions and Their Phenomenology

The Arkani-Hamed-Dimopoulos-Dvali and the Randall-Sundrum models with extra spacelike dimensions, recently proposed as a solution to the hierarchy problem, are reviewed. We discuss their basic properties and phenomenological effects of particle interactions at high energies, predicted whithin these models.

A brief introduction to the theory and phenomenology of soft interactions is given, focusing on total and elastic cross sections and multiparticle production.

These lectures give an introduction to thermal perturbation theory, hard thermal loops, and their use in a nonperturbative, approximately self-consistent resummation of the thermodynamical potentials of quantum chromodynamics.

We study the neutral current flavour changing rare decay mode B → Xs+ missing energy within the framework of theories with large extra spatial dimensions. The corresponding Standard Model signature is B → Xs + νν̄. But in theories with large extra dimensions, it is possible to have scalars and gravitons in the final state making it quite distinct from any other scenario where there are no gravit...
