We present a measurement of the W-boson mass, MW, using data corresponding to 2.2 fb−1 of integrated luminosity collected in pp¯ collisions at s√=1.96 TeV with the CDF II detector at the Fermilab Tevatron. The selected sample of 470 126 W→eν candidates and 624 708 W→μν candidates yields the measurement MW=80387±12(stat)±15(syst)=80387±19 MeV/c2. This is the most precise single measurement of the W-boson mass to date.

Abstract
We present a measurement of the W-boson mass, MW, using data corresponding to 2.2 fb−1 of integrated luminosity collected in pp¯ collisions at s√=1.96 TeV with the CDF II detector at the Fermilab Tevatron. The selected sample of 470 126 W→eν candidates and 624 708 W→μν candidates yields the measurement MW=80387±12(stat)±15(syst)=80387±19 MeV/c2. This is the most precise single measurement of the W-boson mass to date.File in questo prodotto:
