Abstract
We have measured the -boson mass using data corresponding to of integrated luminosity collected in collisions at with the CDF II detector at the Fermilab Tevatron collider. Samples consisting of 470 126 candidates and 624 708 candidates yield the measurement . This is the most precise measurement of the -boson mass to date and significantly exceeds the precision of all previous measurements combined.

Synopsis
W Marks the Spot
Published 12 April 2012
Two experimental collaborations at Fermilab report a new measurement of the W boson mass that leads to a better prediction of the mass of the Higgs boson.
