First Run II Measurement of the W Boson Mass with CDF
Oliver Stelzer-Chilton (for the CDF Collaboration)
TL;DR
This paper reports the first Run II measurement of the W boson mass using Tevatron data, achieving the most precise single measurement to date with an uncertainty of 48 MeV.
Contribution
It presents a new, highly precise measurement of the W boson mass from Tevatron Run II data, improving the accuracy over previous measurements.
Findings
Measured W boson mass as 80413 ± 48 MeV
Used ~200/pb of data from Tevatron Run II
Achieved the most precise single measurement to date
Abstract
The CDF collaboration has analyzed ~200/pb of Tevatron Run II data taken between February 2002 and September 2003 to measure the W boson mass. With a sample of 63964 W->e nu decays and 51128 W->mu nu decays, we measure M_W = 80413+-34(stat)+-34(syst) MeV. The total measurement uncertainty of 48 MeV makes this result the most precise single measurement of the W boson mass to date.
