The article describes the measurement of the W boson decay width, an important parameter of the standard model. The comparison of the measured value with the theoretical prediction is showing good internal consistency of the theoretical description. The presented measurement is the most accurate single measurement to date. The article summarizes the contributions to the systematic uncertainty.

The article describes the first measurement of the W boson mass using the upgraded Tevatron Run II collider. The result is the most accurate single measurement of the W boson mass. The mass value is an important parameter in the determination of the possible mass range of the as yet unconfirmed Higgs boson. The measurement has reduced the uncertainty of the world average of the W mass value by 15%.
