Résumé :

The analysis presented in this thesis focuses on two methods developed to estimate, from data, the multi-jet and the V+jets background processes for top quark pair production occuring during proton-proton at LHC. Top quark paires are reconstructed using the CMS detector, exploiting the semi-leptonic decay channel. Both methods have been developed and studied using Monte-Carlo simulated data.
