Standard Model high mass Higgs search at CDF
No full textThe CDF collaboration has analyzed almost 6 f b−1 of data collected at the Tevatron Collider at sqrt(s) = 1.96 TeV to search for Standard Model Higgs boson through the decay into W+W−. Starting from events with two leptons, advanced analysis techniques are applied to better discriminate signal from background. The Higgs sensitivity is maximized combining together analysis that exploit different event topologies. No significant excess over the expected background is observed and data is used to set a limit in units of Standard Model expectations. The limit plays a fundamental role in the Higgs search excluding the existence of this particle with mass between 158 and 175 GeV/c2 when combined with D0, the other Tevatron experiment

No full textStudies of high-transverse momentum jet substructure and top quarks produced in 1.96 TeV proton-antiproton collisions
No full textResults of a study of the substructure of the highest transverse momentum (pT) jets observed by the CDF Collaboration are presented. Events containing at least one jet with pT > 400 GeV/c in a sample corresponding to an integrated luminosity of 5.95 fb−1, collected in 1.96 TeV proton-antiproton collisions at Fermilab Tevatron Collider

QCD physics at CDF
Full text linkThe CDF collaboration is engaged in a broad program of QCD measurements at the Fermilab Tevatron Collider. I will discuss inclusive jet production at center-of-mass energies of 1800 GeV and 630 GeV, properties of events with very high total transverse energy and dijet angular distributions

High {Sigma}E{sub {Tau}} multijets at CDF
No full textThe CDF collaboration has studied properties of 3-, 4- and 5-jet events with very high total transverse energy. An appropriate set of kinematic variables is described and two calculations based on QCD and with a phase space model. The QCD calculations are in reasonably good agreement with the data

High E{sub T} jet cross sections at CDF
No full textThe inclusive jet cross section for {ital p}{ital {anti p}} collisions at {radical}s = 1.8 TeV as measured by the CDF collaboration will be presented. Preliminary CDF measurements of the {Sigma} E{sub T} cross section at {radical}s = 1.8 TeV and the central inclusive jet cross section at {radical}s = 0.630 TeV will also be shown

Electroweak physics at CDF
Full text linkThe CDF collaboration is engaged in a broad program of electroweak measurements. The production of WW, WZ, ZZ, W{sub {gamma}}, Z{sub {gamma}} and the high mass Drell Yan charge asymmetry will be discussed, along with a status report on extracting a new W mass from the most recent 90 pb{sup {minus}1} data sample
