Measurement of the Helicity of W Bosons in Top-Quark Decays
A. Abulencia
We measure the branching fraction of the top quark to longitudinally and right-handed polarized bosons, and , using approximately 200 pb of collisi…
A compact starburst ring traced by clumpy OH megamaser emission
R. Parra, J. E. Conway, M. Elitzur +1
We model the OH megamaser emission from the luminous infrared galaxy IIIZw35 as arising from a narrow rotating starburst ring of radius 22 pc enclosing a mass of 7 x 10^6 Msun. We…
Search for Lambda_b -> p pi and Lambda_b -> p K decays in p-pbar collisions at sqrt(s) = 1.96 TeV
CDF Collaboration, D. Acosta
We report on a search for Lambda_b -> p pi- and Lambda_b -> p K- (and charge conjugate) decays in p-pbar collisions at sqrt(s) = 1.96 TeV using 193 pb-1 of data collected by CDFII…
Search for W and Z Bosons in the Reaction \bar{p}p \to 2 jets + γat \sqrt{s} = 1.8 TeV
CDF collaboration, D. Acosta
We present a study of the dijet invariant mass distribution for the reaction $\pbp \to 2 $jets, at a center of mass energy of 1.8 TeV, using data collected by the CDF experim…
Measurement of the azimuthal angle distribution of leptons from W boson decays as a function of the W transverse momentum in proton-antiproton collisions at sqrt(s)=1.8 TeV
D. Acosta
We present the first measurement of the A_2 and A_3 angular coefficients of the W boson produced in proton-antiproton collisions. We study W-> e+nu and W-> mu+nu candidate events p…
Measurement of the Cross Section for Production in Collisions using the Kinematics of Lepton+Jets Events
CDF Collaboration, D. Acosta
We present a measurement of the top pair production cross section in collisions at =1.96 TeV. We collect a data sample with an integrated luminosity of 194$\pm…
Combination of CDF and D0 Limits on a Gauge Mediated SUSY Model Using Diphoton and Missing Transverse Energy Channel
V. Buescher, R. Culbertson, J. Conway +11
We combine the results of the CDF and D0 searches for chargino and neutralino production in Gauge-Mediated SUSY using the two-photon and missing Et channel. The data are p-pbar col…
Search for Long-Lived Doubly-Charged Higgs Bosons in p-pbar Collisions at sqrt{s} = 1.96 TeV
D. Acosta
We present a search for long-lived doubly-charged Higgs bosons (H^{\pm \pm}), with signatures of high ionization energy loss and muon-like penetration. We use 292/pb of data collec…
Continuum EVN and MERLIN observations of Ultra Luminous Infrared Galaxies
A. G. Polatidis, J. E. Conway
Radio imaging of ULIR galaxies is ideal to explore the connection between the starburst and the AGN phenomenon since it is unaffected by dust obscuration, and provides the required…
