This is the closeout report for the grant for experimental research at the energy frontier in high energy physics. The report describes the precise measurement of the W boson mass at the CDF experiment at Fermilab, with an uncertainty of ≈ 12 MeV, using the full dataset of ≈ 9 fb-1 collected by the experiment up to the shutdown of the Tevatron in 2011. In this analysis, the statistical and most of the experimental systematic uncertainties have been reduced by a factor of two compared to the previous measurement with 2.2 fb-1 of CDF data. This research has been the culmination of the PI's track record of producing world-leading measurements of the W boson mass from the Tevatron. The PI performed the first and only measurement to date of the W boson mass using high-rapidity leptons using the D0 endcap calorimeters in Run 1. He has led this measurement in Run 2 at CDF, publishing two world-leading measurements in 2007 and 2012 with total uncertainties of 48 MeV and 19 MeV respectively. The analysis of the final dataset is currently under internal review in CDF. Upon approval of the internal review, the result will be available for public release.

Download First Measurement of the W Boson Mass with CDF in Run 2 Book in PDF, ePub and Kindle
This thesis describes a first measurement of the W Boson mass through the decay into a muon and a neutrino in Run 2 of the Tevatron. The W Bosons are produced in proton-antiproton collisions at a center of mass energy of 1.96 TeV. The data sample used for this analysis corresponds to 200 pb-1 recorded by the upgraded Collider Detector at Fermilab. The most important quantity in this measurement is the momentum of the muon measured in a magnetic spectrometer which is calibrated using the two quarkonium resonances J/? and Y(1S). Systematic uncertainties arise from the modeling of the recoil when the W Boson is produced, the momentum calibration, the modeling of W Boson production and decay dynamics and backgrounds. The result is: MW = 80408 ± 50(stat.) ± 57(syst.) MeV/c2.

Download Measurement of the W Boson and Top Quark Masses at CDF. Book in PDF, ePub and Kindle
We report on the measurements of the W boson and top-quark masses with the CDF II detector in p{bar p} collisions at {radical}s = 1.96 TeV at the Fermilab Tevatron. We highlight the major features and uncertainties for the W mass measurement. The top-quark mass measurements are presented in each t{bar t} decay channels. The combination of the most precise measurements from CDF to date leads to M{sub top} = 172.4 {+-} 1.5(stat.) {+-} 2.2(sys.) GeV/c{sup 2}, corresponding to a relative uncertainty of 1.5%.

Download Precise Measurement of the $W$-boson Mass with the CDF II Detector Book in PDF, ePub and Kindle
We have measured the W-boson mass M{sub W} using data corresponding to 2.2 fb−1 of integrated luminosity collected in p{bar p} collisions at √s = 1.96 TeV with the CDF II detector at the Fermilab Tevatron collider. Samples consisting of 470 126 W → e? candidates and 624 708 W →?? candidates yield the measurement M{sub W} = 80 387 ± 12{sub stat} ± 15{sub syst} = 80 387 ± 19 MeV/c2. This is the most precise measurement of the W-boson mass to date and significantly exceeds the precision of all previous measurements combined.

The W Bosons are produced in proton-antiproton collisions at a center of mass energy of 1.96 TeV. The data sample used for this analysis corresponds to 200 pb{sup -1} recorded by the upgraded Collider Detector at Fermilab. The most important quantity in this measurement is the momentum of the muon measured in a magnetic spectrometer which is calibrated using the two quarkonium resonances J/{Psi} and {Upsilon}(1S). Systematic uncertainties arise from the modeling of the recoil when the W Boson is produced, the momentum calibration, the modeling of W Boson production and decay dynamics and backgrounds. The result is: M{sub W} = 80408 {+-} 50(stat.) {+-} 57(syst.) MeV/c{sup 2}.
