Cette thèse décrit une mesure de la masse du boson W avec le détecteur ATLAS. La mesure exploite les données enregistrées par ATLAS en 2011, a une énergie dans le centre de masse de 7 TeV et correspondant à une luminosité intégrée de 4.6 inverse femtobarn. Les mesures sont faites par ajustement aux données de distributions en énergie transverse des leptons charges et en masse transverse du boson W obtenues par simulation, dans les canaux électron et muon, et dans plusieurs catégories cinématiques. Les différentes mesures sont en bon accord et leur combinaison donne une valeur de m_W = 80371.1 ± 18.6 MeV. La valeur mesurée est compatible avec la moyenne mondiale des mesures existantes, m_W = 80385 ± 15 MeV, et l'incertitude obtenue est compé...
