The purpose of this research in the area of theoretical particle physicsis to study aspects of supersymmetry and supergravity, which are mainingredients in the description and analysis of superstring theory.Superstring theory is the major candidate theory for the study of thefundamental constituents of matter as well as the unification of all the forces between them, including gravity. The viability of superstringtheory depends crucially on the existence of supersymmetry, a conceptthat tells us that at some fundamental level elementary particles, thoughsuperficially distinct in their properties, share an underlying identitywhich allows them to be considered as different facets of a singleentity. By studying supersymmetric theories, of which supergravityis the one relevant for string theory, we learn how to analyze it and howto perform calculations and gain information which ultimatelywill allow us to confirm that with this beautiful theory we haveindeed reached the goal of understanding how Nature works at the mostbasic level.

本研究的目的是在理论粒子物理学领域研究超对称性和超引力，这是超弦理论的描述和分析的主要成分。超弦理论是研究物质的基本组成以及它们之间所有力的统一的主要候选理论，包括引力。超弦理论的可行性关键取决于超对称性的存在，这个概念告诉我们，在某些基本水平上，基本粒子虽然表面上性质不同，但它们有一个潜在的同一性，这使得它们可以被认为是一个单一实体的不同方面。通过研究超对称理论，其中超引力是与弦论相关的理论，我们学习如何分析它，如何执行计算并获得信息，最终将使我们能够确认，通过这个美丽的理论，我们确实达到了理解自然界如何在最基本的水平上运作的目标。
