Relic abundances from the Boltzmann equation
Observational data that support the existence of dark matter (DM) has been largely documented, pointing to the presence of a non-baryonic matter that is responsible for around 25% of the energy budget of the Universe. However, such type of matter has not been detected so far, and the standard model...

Conselho Nacional de Desenvolvimento Científico e Tecnológico - CNPq Dados observacionais que suportam a existência de matéria escura (ME) têm sido amplamente documentados, apontando para a presença de uma matéria não barionica, responsável por cerca de 25% da quantidade de energia do Universo. Contudo, tal tipo de matéria não foi detectada até o momento e o modelo padrão de física de partículas (MP) não possui uma explicação para ME. Neste trabalho, as partículas massivas fracamente interagentes (WIMPs) são apresentadas. É, então, o objetivo principal mostrar que estes candidatos à ME geram a abundância necessária para obter a quantidade estimada de ME no Universo. Esse resultado é obtido através da solução da equação de Boltzmann no cenário do Universo primordial. 2021-12-06T22:17:51Z 2021-12-06T22:17:51Z 2021-07-30 masterThesis RAMOS, Camila Pereira.

description |
Observational data that support the existence of dark matter (DM) has been largely
documented, pointing to the presence of a non-baryonic matter that is responsible for
around 25% of the energy budget of the Universe. However, such type of matter has not
been detected so far, and the standard model of particle physics (SM) does not have an
explanation for DM. In this work, the weakly interacting massive particles (WIMPs), the
main candidates for DM, are presented. It is then the main goal to show that this DM
candidate generates the abundance required to obtain the estimated amount of DM in the
Universe. This result is obtained by solving the Boltzmann equation, in the early Universe scenario. |
