Resumo: O fluxo de raios cósmicos de ultra-alta energia (superiores a 10^18 eV) que chega ao topo da atmosfera é baixo, tal que torna-se necessário estudar em detalhes os chuveiros atmosféricos extensos de modo a se determinar a composição e a energia da partícula primária. Dispõe-se de algoritmos que simulam processos de QED e QCD, e descrevem a difusão das partículas na atmosfera, fornecendo o estado (x, p, id, t) de cada uma. Entretanto, é também necessário parametrizar as funções que descrevem sua distribuição ao longo da cascata atmosférica. O método da entropia máxima (MEM) permite que se parametrize a distribuição de partículas em função dos momentos estatísticos esses perfis, que são menos afetados pelo ruído. A maximização da entropia também permite que a distribuição seja inferida minimizando o enviesamento que ocorre, por exemplo, no ajuste de curvas tradicionalmente realizado. No presente trabalho foi estudada aplicação do MEM na análise do perfil longitudinal das componentes eletrônica e muônica geradas por simulação no CORSIKA, já conhecendo as características da partícula primária, de forma a avaliar os benefícios dessa metodologia no estudo de chuveiros atmosféricos
Abstract: The flux of ultra-high energy cosmic rays (above 10^18 eV) that reach the upper atmosphere is low, so that it is necessary to thoroughly study air showers in order to determine the composition and energy of the primary particle. There are algorithms that simulate QED and QCD processes, and track the particle diffusion in the atmosphere, providing the state (x, p, id, t) of each one. Still, it is also necessary to parameterize the functions that describe its distribution throughout the atmospheric cascade. The maximum entropy method (MEM) allows the parameterization of the particle distribution with the statistical moments as variables, which are less affected by noise. The maximum entropy also allows the inference of the distribution minimizing the bias, which is high in inference processes such as the traditional curve fitting. The application of MEM in the analysis of the longitudinal profile of the electronic and muonic components generated by simulation with CORSIKA was the object of study in this research work, having as a prior the characteristics of the primary particle, in order to evaluate the benefits of the method in the study of air showers

Resumo: Neste trabalho, estudamos os métodos de estatística bayesiana e máxima entropia na análise de dados em eventos de raios cósmicos. Inicialmente, fizemos um resumo sobre o desenvolvimento da física de raios cósmicos em que descrevemos alguns resultados teóricos e experimentais recentes. A seguir, apresentamos uma breve revisão do método bayesiano e o aplicamos na determinação da composição em massa dos primários em eventos de raios cósmicos. Além disso, introduzimos o método de máxima entropia e propomos um método de parametrização do perfil longitudinal de chuveiros atmosféricos extensos. Em todas as aplicações, foram mostrados os algoritmos desenvolvidos e os resultados obtidos a partir de dados de eventos simulados. Os resultados indicaram que tais métodos podem ser utilizados satisfatoriamente como ferramentas na análise de dados em eventos de raios cósmicos
Abstract: In this work, we study bayesian statistics and maximum entropy methods in cosmic ray events data analysis. At first, we summarized developments in cosmic rays physics, describing some recent theoretical and experimental results. We present briefly a review of bayesian method and apply it to the problem of determining mass composition primary cosmic ray events. Moreover, we introduce the maximum entropy method and propose a method for the parametrization of the longitudinal profile of extensive air showers. In all applications, the algorithms developed and the results obtained from simulated event data were shown. The results suggested that such methods can be satisfactorily used as tools in cosmic rays events data analysis
