Abstract:

The Standard Model of particle physics has been enormously successful in predicting a wide range of phenomena in particle physics. Many high precision electroweak measurements are currently carried out at the Tevatron collider to test the theoretical predictions and search for new physics. In this talk, I will mainly focus on the recent high precision measurements of the W boson mass and width at D0 using 1/fb of Run II data. The mass has been measured with a precision of 0.05% and the width has been measured with a precision of 3.5%. Both of them are the most precise measurements from one single experiment to date. The W boson mass result can also be used to make constraints on the mass of the Higgs boson - the last particle remaining to be discovered in the Standard Model.
