ar X iv : h ep - p h / 01 11 02 7 v 2 1 7 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 within 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.

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...

Abstract The twin Higgs mechanism has recently been proposed to solve the little hierarchy problem. We study the implementation of the twin Higgs mechanism in left-right models. At TeV scale, heavy quark and gauge bosons appear, with rich collider phenomenology. In addition, there are extra Higgses, some of which couple to both the Standard Model fermion sector and the gauge sector, while other...
