Abstract:

We present a search for ZZ and ZW vector boson pair production in pp̄ collisions at s=1.96TeV using the leptonic decay channels ZZ→llνν, ZZ→lll′l′, and ZW→lll′ν. In a data sample corresponding to an integrated luminosity of 194pb-1 collected with the Collider Detector at Fermilab, 3 candidate events are found with an expected background of 1.0±0.2 events. We set a 95% confidence level upper limit of 15.2pb on the cross section for ZZ plus ZW production, compared to the standard model prediction of 5.0±0.4pb. © 2005 The American Physical Society.

CRESST cryogenic dark matter search

Abstract:

The CRESST Phase II experiment at Gran Sasso is using 300 g scintillating CaWO4 crystals as absorbers for direct WIMP (weakly interactive massive particles) detection. The phonon signal in the CaWO4 crystal is registered in coincidence with the light signal, which is measured with a separate cryogenic light detector. The absorber crystal and the silicon light detector are read out by tungsten superconducting phase transition thermometers (W-SPTs). As a result an active discrimination of the electron recoils against nuclear recoils is achieved. Results on the properties of the detector modules and on the WIMP sensitivity are presented.

Abstract:

Using the data collected with the DO detector at √ s = 1-96 TeV, for integrated luminosities of about 180 pb-1, we have measured the ratio of inclusive cross sections for pp̄ → Z + b jet to pp̄ → Z + jet production. The inclusive Z + b-jet reaction is an important background to searches for the Higgs boson in associated ZH production at the Fermilab Tevatron collider. Our measurement is the first of its kind, and relies on the Z → e+e- and Z → μ+ μ- modes. The combined measurement of the ratio yields 0.021 ± 0.005 for hadronic jets with transverse momenta pT > 20 GeV/c and pseudorapidities |η| < 2.5, consistent with next-to-leading-order predictions of the standard model. © 2005 The American Physical Society.
