A Precision Measurement of the W Boson Mass with 1 Inverse Femtobarn of DZero Run IIa Data
- Univ. of Notre Dame, IN (United States)
This thesis is a detailed presentation of a precision measurement of the mass of the W boson. It has been obtained by analyzing W → ev decays. The data used for this analysis was collected from 2002 to 2006 with the D0 detector, during Run IIa of the Fermilab Tevatron collider. It corresponds to a total integrated luminosity of 1 fb-1. With a sample of 499,830 W → ev candidate events, we obtain a mass measurement of MW = 80.401 ± 0.043 GeV. This is the most precise measurement from a single experiment to date.
