Abstract in Portuguese
O objetivo desse projeto é estudar e analisar cordas cósmicas com módulos excitados não-abelianos e as interferências da variação de seus parâmetros nos perfis de resultados obtidos até o momento. Para isso iniciamos com uma introdução ao modelo de cordas cósmicas e vórtices na teoria de campos, explicando a quebra espontânea de simetria e o mecanismo de Higgs, partimos para a solução em forma de vórtice(1) que da origem a corda cósmica, falamos um pouco sobre cordas cósmicas supercondutoras (2) e finalmente chegamos nas cordas de Shifman(3, 4) que é onde fazemos a nossa análise, simulações numéricas e encontramos os resultados. As simulações numéricas nos mostram.

Abstract in English
The objective of this project is to study and analyze cosmic strings with non-abelian excited modules and the interference of the variation of their parameters in the profiles of results obtained so far. Thereunto, we start with an introduction to the model of cosmic strings and vortices in field theory, explaining the spontaneous symmetry breaking and the Higgs mechanism, then we go to the solution in the form of a vortex(1) that gives rise to the cosmic string, we talk a little about strings superconducting cosmic strings(2) and finally we arrive at the Shifman strings(3, 4) which is where we do our analysis, numerical simulations and find the results. Numerical simulations show us.
