Reconstruction of the W mass and width at and above WW threshold at FCC-ee

In the Standard Model theory, the mass of the W boson is predicted with an uncertainty of 4 MeV/c$^{2}$ whereas the current experimental accuracy is of 12 MeV/c$^{2}$. The present uncertainty is currently limiting the sensitivity to possible effects of new physics through the global fit of the elect...
