No. of bitstreams: 1 lima_ds_me_guara.pdf: 569707 bytes, checksum: 2062a40c0ffdddb4c5801a33f1f13f9d (MD5) Previous issue date: 2018-02-05 / Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES) / Nesta dissertação serão analisados os dois modelos conhecidos na literatura que descrevem partículas massivas de spin 3/2 em D=2+1 dimensões. Essa análise será feita, assim como nos trabalhos relacionados aos bósons (spin 1, spin 2 e spin 3), via procedimento de Imersão de Calibre de Noether (ICN), Solda generalizada, análise de vínculos e condições de Fierz-Pauli. Através de argumentos de simetria, via ICN, apresentaremos uma forma de relacionar os dois modelos e mostraremos que é possível construir um novo modelo de terceira ordem em derivadas. Apresentaremos um modelo de dubleto de segunda ordem em derivadas de onde é possível obter os demais modelos auto-duais da teoria. A partir da aplicação da ICN no modelo de dubleto construiremos um novo modelo, de quarta ordem em derivadas, análogo a versão linearizada da chamada " New Massive Gravity". / In this master's thesis we will analyze the two known models in the literature wich describe massive spin 3/2 particles in D = 2 + 1 dimensions. This analysis will be done, as was previously done on works related to the bosons (spin- 1 , spin- 2 and spin- 3 ), via Noether gauge embedment (NGE) procedure, generalized soldering, hamiltonian constraints analysis and Fierz-Pauli conditions. Through symmetry arguments, by NGE, we will present a way of relating the two models and show that it is possible to construct a new model in third order derivatives. We will show a second order derivative doublet-model whence it is possible to obtain the other self-dual models of the theory. From the application of NGE in the dublet model we will construct a new model, wich has a fourth-order derivative term, analogue to the linearized version of the so-called "New Massive Gravity"
