Energy Frontier
The CDF Silicon Vertex Detector plays a critical role in most analyses at CDF, including searches for the Higgs boson, new physics signatures, measurements of Bs-mixing, top quark and W boson masses. Originally designed to withstand up to 3 1/fb, its life has spanned over 11 1/fb of integrated delivered luminosity with surprisingly good performance. In this talk we will present details of...

Energy Frontier
We use an unbinned likelihood fit, as used in previous precision top quark mass measurements, with events from lepton + jet top quark decays where the lepton has been identified as a hadronically decaying tau. We use ppbar collisions at 1.96 TeV at CDF. Events require a single lepton identified as a hadronic tau, missing Et, and 4 jets of which at least one must be tagged as a b jet. The...

Energy Frontier
We present a model-independent measurement of t-channel electroweak production of single top quarks in ppbar collisions at center of mass energy of 1.96 TeV. Using 5.4 fb^−1 of integrated luminosity collected by the D0 detector at the Fermilab Tevatron Collider, and selecting events containing an isolated electron or muon, missing transverse energy and one or two jets originating from the...

Energy Frontier
We present a measurement of the b-tagging efficiency using 32pb-1 of data collected in 2010 with the CMS detector operating at the proton-proton LHC with sqrt(s)=7 TeV. The measurement is based on data samples that have a least two reconstructed jets and a non-isolated muon close to one of the jets. The measurements are made as a function of the jet pT and eta. Results are presented for...

Energy Frontier: Higgs Physics
We present a search for the Standard Model Higgs boson produced in association with a W boson in proton-antiproton collisions at a center-of-mass energy of 1.96 TeV. We search a dataset corresponding to an integrated luminosity of 5.7 fb-1. The analysis uses the channel where the Higgs boson decays to a bottom-antibottom quark pair and the W boson decays leptonically. Therefore, we select...

Energy Frontier: Higgs Physics
We present a search for Standard Model Higgs boson (h) production in pp-bar collisions at a center-of-mass energy of 1.96 TeV. for this analysis, we use the data collected with the CDF II detector. We consider h decays into two W bosons of which one decays into a lepton plus a neutrino and another decays into two jets. This is the dominant decay mode for h mass larger than 135 GeV. This decay...

Energy Frontier: Higgs Physics
An overview of a search for the Higgs boson in the H \rightarrow \tau\tauハdecay channel in data collected with CDF detector at the Tevatron collider is presented. To fully explore the discovery potential of this channel sophisticated methods are required for identification and energy measurements of tau leptons decaying hadronically as well as the for accurate reconstruction of the mass of...

Energy Frontier: Higgs Physics
We present a search for the Standard Model Higgs boson produced in association with a $Z$ boson in the $\ell^+\ell^-b\bar{b}$ $(\ell=e,\mu)$ final state using the CDF detector. The latest iteration of this analysis has benefited from several improvements, including multivariate
lepton identification, the inclusion of additional triggers based on missing transverse energy, and the addition of...
