Procura do bóson de Higgs no canal de decaimento H → W+ W- →µ+νµ-ν utilizando a técnica de elemento de matriz no experimento CMS do CERN

Abstract

We present the activities that were developed during the Master, which aimed at the development of the data analysis technique using the Matrix Element Method (ME) in the Higgs boson search in the CMS experiment. The proposal was to use a data analysis technique relatively new known as Matrix Element Method (ME). This technique was developed and used recently for application in the top quark physics in D0 and CDF experiments at the Tevatron (Fermilab). However, there are no studies involving the use of it in the physics of the Higgs at the LHC. The ME method was applied in the Higgs boson search in the decay channel H → W+ W- →µ+νµ-ν , which the current studies indicate as being one of the channels with the highest potential for discovery, especially at this early stage in which the statistic is still very limited.
