Models with Extra Dimensions and Their Phenomenology

TL;DR

This paper reviews models with extra spatial dimensions, focusing on their properties and how they affect particle interactions at high energies, aiming to address the hierarchy problem.

Contribution

It provides a comprehensive overview of the Arkani-Hamed-Dimopoulos-Dvali and Randall-Sundrum models, highlighting their phenomenological implications.

Findings

Extra dimensions can modify particle interaction signatures at high energies.

These models offer potential solutions to the hierarchy problem.

Phenomenological effects include new particle states and altered scattering processes.

Abstract

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.
