As one of the most important parameters in the Standard Model (SM), the mass of the W boson (mW) is currently the limiting factor in our ability to tighten the constraint on the mass of the Higgs boson (mH) within the SM framework. This review summarizes the world's most precise mW measurement to date using ~2.2 fb -1 data collected in [Formula: see text] collisions at [Formula: see text] with the CDF II detector at the Fermilab Tevatron Collider. This review will first describe the motivation for improving the precision of mW measurement, then present the details of this analysis, followed by the final measurement result and the future perspective.
