Abstract:

We present the first measurement of polarization and CP-violating asymmetries in a Bs0 decay into two light vector mesons, Bs0→φφ, and an improved determination of its branching ratio using 295 decays reconstructed in a data sample corresponding to 2.9fb-1 of integrated luminosity collected by the CDF experiment at the Fermilab Tevatron collider. The fraction of longitudinal polarization is determined to be fL=0.348±0.041(stat)±0.021(syst), and the branching ratio B(Bs0→φφ)=[2.32±0.18(stat)±0. 82(syst)]×10-5. Asymmetries of decay angle distributions sensitive to CP violation are measured to be Au=-0.007±0. 064(stat)±0.018(syst) and Av=-0.120±0.064(stat) ±0.016(syst). © 2011 American Physical Society.

Abstract:

We present a measurement of the top quark mass (Mtop) in the all-hadronic decay channel using 5.8 fb^{-1} of proton-antiproton data collected with the CDF II detector at the Fermilab Tevatron Collider. Events with 6 to 8 jets are selected by a neural network algorithm and by the requirement that at least one of the jets is tagged as a b quark jet. The measurement is performed by a likelihood fit technique, which determines simultaneously Mtop and the jet energy scale (JES) calibration. The fit yields a value of 172.5 +- 1.4(stat) +-1.0(JES) +-1.1(syst) GeV/c^2.

Abstract:

This paper presents a search for standard model Higgs boson production in association with a $W$ boson using events recorded by the CDF experiment in a dataset corresponding to an integrated luminosity of 5.6 fb-1. The search is performed using a matrix element technique in which the signal and background hypotheses are used to create a powerful discriminator. The discriminant output distributions for signal and background are fit to the observed events using a binned likelihood approach to search for the Higgs boson signal. We find no evidence for a Higgs boson, and 95% confidence level (C.L.) upper limits are set on the Higgs boson production rate. The observed limits range from 3.5 to 37.6 relative to the standard model expectation for Higgs boson masses between 100 and 150 GeV. The 95% C.L. expected limit is estimated from the median of an ensemble of simulated experiments and varies between 2.9 and 32.7 relative to the production rate predicted by the standard model over the Higgs boson mass range studied.
