标题： Phenomenology and Cosmology of Supersymmetric Grand Unified Theories

摘要： 本论文的主要目标之一是寻找来自超对称理论的通胀模型，这些模型与最近的宇宙学数据相容，特别是与WMAP3数据对光谱指数的测量相容。 一个特定的粒子物理模型，即具有Yukawa近似统一的扩展超对称Pati-Salam模型，被彻底研究了其宇宙学特性，并发现它包含了一些可能与最新数据相容的通胀情景。 对这些情景的研究揭示了若干宇宙学模型的变化，这些变化可能在宇宙学研究中具有重要意义。 显示英文摘要

摘要： One of the major objectives of this dissertation has been the seek for inflationary models, coming from supersymmetric theories, which are compatible with recent cosmological data and, more specifically, with measurements of the spectral index from the WMAP3 data. A particular particle physics model, the extended SUSY Pati-Salam model with Yukawa quasi-unification, was examined thoroughly with respect to its cosmology and it was found that it incorporates a number of inflationary scenarios which can become compatible with recent data. The study of these scenarios brought out variations of cosmological models which might be important in cosmological research.
