A Precision Measurement of the W Boson Mass with 1 Fb−1 of Dø Run Iia Data

چکیده
by Jyotsna Osta This thesis is a detailed presentation of a precision measurement of the mass of the W boson. It has been obtained by analyzing W → eν decays. The data used for this analysis was collected from 2002 to 2006 with the DØ 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 → eν 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. Dedicated to my family, teachers and friends I am because they are The woods are lovely, dark and deep, But I have promises to keep, And miles to go before I sleep, And miles to go before I sleep. “Stopping By Woods on a Snowy Evening” by Robert Frost

Measurement of Properties of Electroweak Bosons with the DØ Detector
This article reports three analyses of W and Z boson properties from the DØ experiment at the Fermilab Tevatron. The W boson mass measurement using 1 f b −1 DØ data is presented. This measurement reaches a 43 MeV precision on the W boson mass, which is currently the most precise result from a single experiment. It is used to place indirect constraint on the mass of the hypothetical Higgs boson....
متن کامل6 M ay 2 00 2 FIRST DATA FROM DØ IN RUN 2
Run 2 of the Tevatron collider at Fermilab has begun in the spring of 2001. During its first year of operation the Tevatron has delivered an integrated luminosity of approximately 30 pb −1 to the DØ experiment. These data have been used to commission the detector. The progress in understanding the detector performance and the prospects for an exciting physics program to be carried out in the ne...
متن کاملMeasurement of the W Boson Mass with 1 fb − 1 of D 0 Run II Data
We present the most precise single measurement of the W boson mass using data collected with the D0 experiment. An integrated luminosity of 1 fb −1 yields 499,830 W → eν candidates. With this sample we measure M W = 80.401 ± 0.043 GeV.
متن کاملMeasurement of top quark properties at √ s = 1 . 96 TeV using the DØ detector
Since the discovery of the top quark in 1995 at the Fermilab Tevatron collider, top quark properties have been measured with ever higher precision. The increase in data has provided the opportunity to probe many new aspects of the top quark sector. In addition to an updated measurement of the helicity of the W boson in t ¯ t events using 5.4 fb −1 , this review briefs three new analyses perform...

We combine results from CDF and DØ on direct searches for a standard model (SM) Higgs boson (H) in p¯ p collisions at the Fermilab Tevatron at √ s = 1.96 TeV. Compared to the previous Higgs Tevatron combination, more data and new channels (W H → τ νb ¯ b, V H → τ τ b ¯ b/jjτ τ , V H → jjb ¯ b, t ¯ tH → t ¯ tb ¯ b) have been added. Most previously used channels have been reanalyzed to gain sensi...
