AB  - he Standard Model is the most powerful theory describing the fundamental constituents of matter and their interactions. Historically, relations between the fundamental parameters of the SM have been used to predict the mass of the top quark and to put constraints on the Higgs boson mass before these particles were experimentally confirmed. Today, the indirect determination of the W-boson mass from global electroweak fits outperforms the precision of its experimentally measured value. An improved experimental measurement is, therefore, one of the goals of the LHC physics program, aiming to test the overall consistency of the Standard Model and possibly reveal new, conflicting phenomena.The seminar will discuss the improved measurement of the mass of the W boson at a centre-of-mass energy of 7 TeV, recently released by the ATLAS Collaboration. The previous ATLAS measurement is re-evaluated using a profile likelihood fit, which improves the precision of the mass determination by 15
