Measurement Of Mass And Width Of The Excited Charmed Meson States D10 And D2*0 At Cdf, A. Abulencia, Kenneth A. Bloom, Cdf Collaboration
Kenneth Bloom Publications
We report on precision measurements of the masses and widths of the narrow, orbitally excited states D10 and D2*0 using the CDF II detector at the Fermilab Tevatron. Both states (collectively called D**) are reconstructed in the decay channel D** → D*+ π-. The D2*0 is also reconstructed in the D** → D+ π- channel. Using a data set with an integrated luminosity of 210 pb-1, the measured masses and widths for the D10 are 2421.7 ± 0.7 ± 0.6 MeV/ …

Measurement Of The Azimuthal Angle Distribution Of Leptons FromW Boson Decays As A Function Of The W Transverse Momentum In Pp̅ Collisions At √S = 1.8 Tev, Darin Acosta, Kenneth A. Bloom, Fermilab Collaboration
Measurement Of The Azimuthal Angle Distribution Of Leptons FromW Boson Decays As A Function Of The W Transverse Momentum In Pp̅ Collisions At √S = 1.8 Tev, Darin Acosta, Kenneth A. Bloom, Fermilab Collaboration
Kenneth Bloom Publications
We present the first measurement of the A2 and A3 angular coefficients of the W boson produced in proton-antiproton collisions. We study W → e νe and W → e νe candidate events produced in association with at least one jet at CDF, during Run Ia and Run Ib of the Tevatron at √s =1:8 TeV. The corresponding integrated luminosity was 110 pb-1. The jet balances the transverse momentum of the W and introduces QCD effects in W boson production. The extraction of the angular coefficients is achieved through the direct measurement of the …
Search For Anomalous Semileptonic Decay Of Heavy Flavor Hadrons Produced In Association With A W Boson At Cdf Ii, A. Abulencia, Kenneth A. Bloom, Cdf Collaboration
Search For Anomalous Semileptonic Decay Of Heavy Flavor Hadrons Produced In Association With A W Boson At Cdf Ii, A. Abulencia, Kenneth A. Bloom, Cdf Collaboration
Kenneth Bloom Publications
We present a search for anomalous semileptonic decays of heavy flavor hadrons produced in association with a W boson in proton-antiproton collisions at √s = 1:96 TeV.We use 162 pb-1 of data collected with the CDF II detector at the Fermilab Tevatron Collider. We select events with one W boson and at least one jet with an identified secondary vertex. In the jets with a secondary vertex we look for a semileptonic decay to a muon. We compare the number of jets with both a secondary vertex and a semileptonic decay and the kinematic properties of these jets, with …
Top Quark Mass Measurement Using The Template Method In The Lepton + Jets Channel At Cdf Ii, A. Abulencia, Kenneth A. Bloom, Cdf Collaboration
Top Quark Mass Measurement Using The Template Method In The Lepton + Jets Channel At Cdf Ii, A. Abulencia, Kenneth A. Bloom, Cdf Collaboration
Kenneth Bloom Publications
This article presents a measurement of the top quark mass using the CDF II detector at Fermilab. Colliding beams of protons and antiprotons at Fermilab’s Tevatron (√s = 1.96 TeV) produce top/antitop pairs, which decay to W+W-bb̅; events are selected where one W decays to hadrons and the other W decays to either ℯ or μ plus a neutrino. The data sample corresponds to an integrated luminosity of approximately 318 pb-1. A total of 165 tt̅ events are separated into four sub-samples based on jet transverse energy thresholds and the number of b …
Search For Charged Higgs Bosons From Top Quark Decays In Pp̅ Collisions At √S = 1:96 Tev, A. Abulencia, Kenneth A. Bloom, Cdf Collaboration
Search For Charged Higgs Bosons From Top Quark Decays In Pp̅ Collisions At √S = 1:96 Tev, A. Abulencia, Kenneth A. Bloom, Cdf Collaboration
Kenneth Bloom Publications
We report the results of a search for a charged Higgs boson in the decays of top quarks produced in pp̅ collisions at a center-of-mass energy of 1.96 TeV. We use a data sample corresponding to an integrated luminosity of 193 pb-1 collected by the upgraded Collider Detector at Fermilab. No evidence for charged Higgs production is found, allowing 95% C.L. upper limits to be placed on BR(t→ H+b) for different charged Higgs decay scenarios. In addition, we present in the minimal supersymmetric standard model (mH±, tan β) plane the …

Precision Top-Quark Mass Measurement In The Lepton+Jets Topology In Pp̅ Collisions At √S =1.96 Tev, A. Abulencia, Kenneth A. Bloom, Cdf Collaboration
Kenneth Bloom Publications
We report two measurements of the top-quark mass Mtop using the CDF II detector at the Fermilab Tevatron in a 318 pb-1 data sample of tt̅ events in the lepton + jets final state. One method uses an event-based likelihood technique resulting inMtop = 173.2-2.4+2.6(stat) ± 3.2(syst) GeV/c2 or 173.2-4.0+4.1GeV/c2. The second method reconstructs a top-quark mass in each event using the measured invariant mass of the hadronically decaying W boson to constrain the jet energy scale to obtain a value forMtop of …
Search For Neutral Higgs Bosons Of The Minimal Supersymmetric Standard Model Decaying To Τ Pairs In Pp̅ Collisions At √S = 1:96 Tev, A. Abulencia, Kenneth A. Bloom, Cdf Collaboration
Search For Neutral Higgs Bosons Of The Minimal Supersymmetric Standard Model Decaying To Τ Pairs In Pp̅ Collisions At √S = 1:96 Tev, A. Abulencia, Kenneth A. Bloom, Cdf Collaboration
Kenneth Bloom Publications
We present a search for neutral supersymmetric Higgs bosons decaying to τ pairs produced in pp̅ collisions at √s =1:96 TeV. The data, corresponding to 310 pb-1 integrated luminosity, were collected with the Collider Detector at Fermilab in run II of the Tevatron. No significant excess above the standard model backgrounds is observed. We set exclusion limits on the production cross section times branching fraction to τ pairs for Higgs boson masses in the range from 90 to 250 GeV/c2.
Search For W And Z Bosons In The Reaction P̅P → Two Jets + Γ At √S = 1.8 Tev, Darin Acosta, Kenneth A. Bloom, Cdf Collaboration
Search For W And Z Bosons In The Reaction P̅P → Two Jets + Γ At √S = 1.8 Tev, Darin Acosta, Kenneth A. Bloom, Cdf Collaboration
Kenneth Bloom Publications
We present a study of the dijet invariant mass distribution for the reaction p̅p → two jets + γ + X, at a center of mass energy of 1.8 TeV, using data collected by the CDF experiment. We compare the data to predictions for the production of a photon with two jets, together with the resonant processes p̅p → W/Z + γ +X, in which the W and Z bosons decay hadronically. A fit is made to the dijet invariant mass distribution combining the nonresonant background and resonant processes. We use the result to establish …

Search For R-Parity Violating Supersymmetry Via The Llē Couplings Λ121, Λ122 Or Λ133 In Pp Collisions At √ S = 1.96 Tev, V. M. Abazov, Kenneth A. Bloom, Gregory Snow, Do Collaboration
Search For R-Parity Violating Supersymmetry Via The Llē Couplings Λ121, Λ122 Or Λ133 In Pp Collisions At √ S = 1.96 Tev, V. M. Abazov, Kenneth A. Bloom, Gregory Snow, Do Collaboration
Kenneth Bloom Publications
A search for gaugino pair production with a trilepton signature in the framework of R-parity violating supersymmetry via the couplings λ121, λ122, or λ133 is presented. The data, corresponding to an integrated luminosity of L ≈ 360 pb−1, were collected from April 2002 to August 2004 with the D∅ detector at the Fermilab Tevatron Collider, at a center-of-mass energy of √s = 1.96 TeV. This analysis considers final states with three charged leptons with the flavor combinations eel, μμl, and eeτ (l = e or μ). No evidence for supersymmetry is …
Search For Scalar Leptoquarks In The Acoplanar Jet Topology In Pp Collisions At √ S = 1.96 Tev, V. M. Abazov, Kenneth A. Bloom, Gregory Snow, D0 Collaboration
Search For Scalar Leptoquarks In The Acoplanar Jet Topology In Pp Collisions At √ S = 1.96 Tev, V. M. Abazov, Kenneth A. Bloom, Gregory Snow, D0 Collaboration
Kenneth Bloom Publications
A search for leptoquarks has been performed in 310 pb−1 of data from pp collisions at a center-of-mass energy of 1.96 TeV, collected by the D0 detector at the Fermilab Tevatron Collider. The topology analyzed consists of acoplanar jets with missing transverse energy. The data show good agreement with standard model expectations, and a lower mass limit of 136 GeV has been set at the 95% C.L. for a scalar leptoquark decaying exclusively into a quark and a neutrino.
