    Description
The W boson mass, an important parameter in the Standard Model, has a current measured value of 80.379 GeV with an uncertainty of 12 MeV. At FCC-ee, the expected precision should be reduced to below the 1 MeV level. A Monte-Carlo study is performed using the FCC-ee analysis framework through two decay channels of the W bosons (hadronic and semi-leptonic) at 180 GeV center-of-mass energy to determine the value of the W mass. The W boson mass and uncertainty are extracted from the decay products, the missing momentum and the kinematic constraints of the initial state.
