Abstract
We have measured the W-boson mass M[superscript W] using data corresponding to 2.2 fb[superscript -1] of integrated luminosity collected in pp̅ collisions at √s=1.96 TeV with the CDF II detector at the Fermilab Tevatron collider. Samples consisting of 470 126 W→eν candidates and 624 708 W→μν candidates yield the measurement M[superscript W]=80 387±12[subscript stat.]±15[subscript syst.]=80 387±19 MeV/c[superscript 2]. This is the most precise measurement of the W-boson mass to date and significantly exceeds the precision of all previous measurements combined.
