Electroweak physics prospects for CDF in Run II

PDF Version Also Available for Download.

Description

The CDF collaboration will vigorously pursue a comprehensive program of electroweak physics during Run II at the Tevatron based strongly on the successful Run I program. The Run IIa integrated luminosity goal of 2 fb{sup -1} will lead to a CDF dataset twenty times larger than that collected in Run I. In addition, an increase in the energy of the colliding beams from {radical}s = 1.80 TeV to {radical}s = 1.96 TeV for Run II provides a 10% increase in the W and Z boson production cross sections and a corresponding enlargement of the electroweak event samples.

Description

The CDF collaboration will vigorously pursue a comprehensive program of electroweak physics during Run II at the Tevatron based strongly on the successful Run I program. The Run IIa integrated luminosity goal of 2 fb{sup -1} will lead to a CDF dataset twenty times larger than that collected in Run I. In addition, an increase in the energy of the colliding beams from {radical}s = 1.80 TeV to {radical}s = 1.96 TeV for Run II provides a 10% increase in the W and Z boson production cross sections and a corresponding enlargement of the electroweak event samples. In the near term, CDF expects to collect a dataset with 2-3 times the integrated luminosity of Run I by September of 2003. Utilizing these new datasets CDF will be able to make improved, precision measurements of Standard Model electroweak parameters including M{sub W}, M{sub top}, {Lambda}{sub W}, and sin{sup 2}{theta}{sub W}{sup eff}. The goal of these measurements will be to improve our understanding of the self-consistency of the Standard Model and knowledge of the Higgs boson mass within the model. The top plot in Fig. 1 illustrates our current knowledge of the Standard Model Higgs mass based on measurements of M{sub W} and M{sub top}. The constraints imposed by combined CDF and D0 Run I measurements of M{sub W} (80.456 {+-} 0.059GeV/c{sup 2}) and M{sub top} (174.3 {+-} 5.1GeV/c{sup 2}) are illustrated by the shaded oval region on the plot. The hatched rectangle shows the additional constraint imposed by the recent LEP2 measurement of M{sub W}. The bottom plot in Fig. 1 illustrates the expected improvement in these constraints based on Run II CDF measurements utilizing a 2 fb{sup -1} dataset. The shaded oval region in this plot is based on current estimates of a 40 MeV/c{sup 2} uncertainty for measuring M{sub W} and a 2-3 GeV/c{sup 2} uncertainty for measuring M{sub top}.
