Resumo: In this work we study actions for the superparticle and the superstring using twistor-like constraints. We write BRST charges for the superparticle and the superstring in ten dimensions, and the BRST charge for a particle model in four dimensions in order to make some comparisons. We start showing how twistors appear as geometrical objects parametrizing SO(4)/U(2), and use a generalization of this fact to ten dimensions to construct the corresponding theories. We then show how to obtain the pure spinor superparticle and superstring actions in ten dimensions by gauge-twisting and gauge-fixing the initial theory.

Escrevemos as cargas BRST para a superpartícula e a supercorda em dez dimensões, e a carga BRST para um modelo de partícula em quatro dimensões com a finalidade de fazer algumas comparações. Começamos mostrando como os twistors aparecem como objetos geométricos que parametrizam SO(4)/U(2), e usamos uma generalização deste fato para dez dimensões e assim construir as teorías correspondentes. Então mostramos como obter as ações de espinores puros para a superpartícula e a supercorda em dez dimensões por meio de gauge-twisting e gauge-fixing da teoría inicial.Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES)Universidade Estadual Paulista (Unesp)Berkovits, Nathan JacobUniversidade Estadual Paulista (Unesp)Rocha, Luis Alberto Ypanaqué [UNESP]2016-06-08T16:39:04Z2016-06-08T16:39:04Z2016-04-05info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisapplication/pdfhttp://hdl.handle.net/11449/13943600087121633015015001P77565192274317470enginfo:eu-repo/semantics/openAccessreponame:Repositório Institucional da UNESPinstname:Universidade Estadual Paulista (UNESP)instacron:UNESP2024-01-22T06:25:56Zoai:repositorio.unesp.br:11449/139436Repositório InstitucionalPUBhttp://repositorio.unesp.br/oai/requestopendoar:29462024-01-22T06:25:56Repositório Institucional da UNESP - Universidade Estadual Paulista (UNESP)false
