Search for standard model Higgs boson production in association with a W boson at CDF
Physical Review D - Particles, Fields, Gravitation and Cosmology 85:5 (2012)
Abstract:
We present a search for the standard model Higgs boson production in association with a W boson in proton-antiproton collisions (pp̄→W ±H→νbb̄) at a center of mass energy of 1.96 TeV. The search employs data collected with the CDF II detector which correspond to an integrated luminosity of approximately 2.7fb -1. We recorded this data with two kinds of triggers. The first kind required high-p T charged leptons and the second required both missing transverse energy and jets. The search selects events consistent with a signature of a single lepton (e ±/μ ±), missing transverse energy, and two jets. Jets corresponding to bottom quarks are identified with a secondary vertex tagging method and a jet probability tagging method. Kinematic information is fed in an artificial neural network to improve discrimination between signal and background. The search finds that both the observed number of events and the neural network output distributions are consistent with the standard model background expectations, and sets 95% confidence level upper limits on the production cross section times branching ratio. The limits are expressed as a ratio to the standard model production rate. The limits range from 3.6 (4.3 expected) to 61.1 (43.2 expected) for Higgs masses from 100 to 150GeV/c2, respectively. © 2012 American Physical Society.Search for standard model Higgs boson production in association with a W boson at CDF

Measurement of ZZ production in leptonic final states at sqrt[s] of 1.96 TeV at CDF.
Physical review letters 108:10 (2012) 101801
Abstract:
In this Letter, we present a precise measurement of the total ZZ production cross section in pp collisions at sqrt[s]=1.96 TeV, using data collected with the CDF II detector corresponding to an integrated luminosity of approximately 6 fb(-1). The result is obtained by combining separate measurements in the four-charged (ℓℓℓ' ℓ') and two-charged-lepton and two-neutral-lepton (ℓℓνν) decay modes of the Z boson pair. The combined measured cross section for pp → ZZ is 1.64(-0.38)(+0.44) pb. This is the most precise measurement of the ZZ production cross section in 1.96 TeV pp collisions to date.Measurements of the angular distributions in the decays B→K( *)μ+μ- at CDF
