Experimento CMS - Brasil

Relatório de Atividades 2012

1 IntroduçãoO principal objetivo do experimento CMS é o estudo das leis fundamentais da Natureza em

energias muito altas. Além da busca pelo elusivo bóson de Higgs, a última peça que faltavano Modelo Padrão de Física de Partículas, o CMS é capaz de investigar a existência de novaspartículas e interações. Durante o ano de 2012 o CMS coletou os dados obtidos da colisãode feixes de prótons à energia de centro de massa de 8 TeV. Os resultados das análises dessasobservações foram apresentados em 113 artigos científicos publicados em revistas indexadas.Contando com 56 membros, a participação do grupo brasileiro no experimento resultou, entreoutros, na produção de seis dissertações de mestrado e três teses de doutorado.
