Resumo: In this thesis we study both limits of the AdS/CFT correspondence: the phase space of higher-spin theories, and the insertion of vertex operators in string correlation functions of the pure spinor formulation in $AdS_{5} \times S^{5}$ background. We also compute the equations of motion for Ramond sector of the RNS heterotic ambitwistor string. The study the phase-space of free higher-spin theories uses a formulation obtained from twistors by Penrose and hints the presence of a non-local conformal symmetry. The string scattering in AdS is studied with the BV formalism, appropriate for this background given that the b-ghost is non-holomorphic; we write the amplitude with the insertion of a beta-deformation vertex. For the heterotic ambitwistor system, we obtain the supersymmetry algebra of this theory.

Nós calculamos também as equações de movimento do setor de Ramond para a corda ambitwistor heterótica na descrição RNS. O estudo do espaço de fase das teorias de spin alto usa a formulação obtida por Penrose e dá indícios da presença de uma simetria conforme não-local. A amplitude de espalhamento em AdS é estudada com o formalismo BV, apropriado para este background onde o fantasma b não é holomórfico; nós escrevemos a amplitude com a inserção de um vértice de deformação beta. Para o sistema heterótico, nós obtemos as transformações de supersimetria da teoria.Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES)CAPES 33015015001P7Universidade Estadual Paulista (Unesp)Mikhailov, Andrei [UNESP]mikhailovUniversidade Estadual Paulista (Unesp)Flores, Henrique dos Santos [UNESP]2020-07-23T17:59:11Z2020-07-23T17:59:11Z2019-10-10info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/doctoralThesisapplication/pdfhttp://hdl.handle.net/11449/19302033015015001P7enginfo:eu-repo/semantics/openAccessreponame:Repositório Institucional da UNESPinstname:Universidade Estadual Paulista (UNESP)instacron:UNESP2023-10-18T06:03:57Zoai:repositorio.unesp.br:11449/193020Repositório InstitucionalPUBhttp://repositorio.unesp.br/oai/requestopendoar:29462024-08-05T15:12:45.529372Repositório Institucional da UNESP - Universidade Estadual Paulista (UNESP)false
