Several aspects of theories with extra spatial dimensions will be studied. The main focus will be understanding what the resulting observable consequences for particle and gravitational physics of such models could be, that is understanding the phenomenology of such models. Secondly, the cosmological evolution and the fundamental theory of these models will also be investigated.Models with extra dimensions have shown new avenues to resolve some of the most fundamental problems in particle physics. These include possible explanations for why gravitational interactions are so much weaker than other particle interactions (like electromagnetism), and perhaps even new directions toward understanding the cosmological constant problem pointed out by Einstein. Due to the potential applications of these models it is very important to study them and to find out which of these could describe our Universe. This is the main goal of this project.

将研究具有额外空间维度的理论的几个方面。主要的焦点将是理解这样的模型的粒子和引力物理学的可观测结果是什么，也就是理解这样的模型的现象学。其次，我们也将探讨这些模型的宇宙演化和基本理论，额外维度模型为解决粒子物理中一些最基本的问题提供了新的途径。这些包括解释为什么引力相互作用比其他粒子相互作用（如电磁力）弱得多的可能性，甚至可能是理解爱因斯坦指出的宇宙常数问题的新方向。由于这些模型的潜在应用，研究它们并找出哪些模型可以描述我们的宇宙非常重要。这是该项目的主要目标。
