Resumo
Neste trabalho, concentramos no estudo da Nucleossíntese Primordial, abordando tanto os
processos nucleares nela envolvidos, como sua importância para a história do Universo como
o conhecemos, e para o desenvolvimento do Modelo Cosmológico Padrão. Optamos pela
descrição desse modelo a partir da sua origem como decorrência da Teoria da Relatividade
Geral. Nesse percurso, adentramos no tema do Universo Primordial, onde a nucleossíntese
dos elementos químicos leves e suas abundâncias têm um papel fundamental na evolução do
Universo. Por fim, apresentamos os principais métodos atuais de medida das abundâncias
destes elementos, realizando uma comparação entre as previsões teóricas e os resultados
observacionais.
In this work, we focus on the study of Primordial Nucleosynthesis, addressing the nuclear processes involved in it, as well as its importance for the history of the Universe as we know it, and for the development of the Standard Cosmological Model. We chose to describe this model from its origin as a result of the Theory of General Relativity. Along this path, we get into the theme of the Primordial Universe, where the nucleosynthesis of light chemical elements and their abundance plays a fundamental role in the evolution of the Universe. Finally, we present the main current methods of measuring these abundances, making a comparison between theoretical predictions and observational results.
