No. of bitstreams: 0 Previous issue date: 2006-09-15; Limits are set on anomalous WWγ and WWZ trilinear gauge couplings using W+W-→e+νee-ν̄e, W+W-→e±νeμ νμ, and W+W-→μ+νμμ-ν̄μ events. The data set was collected by the Run II D0 detector at the Fermilab Tevatron Collider and corresponds to approximately 250pb-1 of integrated luminosity at s=1.96TeV. Under t...

No. of bitstreams: 0 Previous issue date: 2006-01-01; We present a search for supersymmetry in the R-parity violating resonant production and decay of smuons and muon sneutrinos in the channels, 2,3,40. We analyzed 0.38fb-1 of integrated luminosity collected between April 2002 and August 2004 with the D0 detector at the Fermilab Tevatron Collider. The obse...

No. of bitstreams: 0 Previous issue date: 2006-09-25; A search for the production of neutral Higgs bosons Φ decaying into τ+τ- final states in pp̄ collisions at a center-of-mass energy of 1.96 TeV is presented. The data, corresponding to an integrated luminosity of approximately 325pb-1, were collected by the D0 experiment at the Fermilab Tevatron Collider...

No. of bitstreams: 0 Previous issue date: 2006-07-24; We have searched for a heavy resonance decaying into a Z+jet final state in pp̄ collisions at a center of mass energy of 1.96TeV at the Fermilab Tevatron collider using the D0 detector. No indication for such a resonance was found in a data sample corresponding to an integrated luminosity of 370pb-1. We...

No. of bitstreams: 0 Previous issue date: 2006-10-30; We present a search for a neutral particle, pair produced in pp̄ collisions at s=1.96TeV, which decays into two muons and lives long enough to travel at least 5 cm before decaying. The analysis uses 380pb-1 of data recorded with the D0 detector. The background is estimated to be about one event. No cand...

No. of bitstreams: 0 Previous issue date: 2006-10-30; We report a search for the standard model (SM) Higgs boson based on data collected by the D0 experiment at the Fermilab Tevatron Collider, corresponding to an integrated luminosity of 260pb-1. We study events with missing transverse energy and two acoplanar b jets, which provide sensitivity to the ZH pr...

No. of bitstreams: 0 Previous issue date: 2006-11-06; A search for direct production of scalar bottom quarks (b) is performed with 310pb-1 of data collected by the D0 experiment in pp̄ collisions at s=1.96TeV at the Fermilab Tevatron Collider. The topology analyzed consists of two b jets and an imbalance in transverse momentum due to undetected neutralinos...

No. of bitstreams: 0 Previous issue date: 2006-11-20; We measure the dimuon charge asymmetry A in pp̄ collisions at a center of mass energy s=1960GeV. The data was recorded with the D0 detector and corresponds to an integrated luminosity of approximately 1.0fb-1. Assuming that the asymmetry A is due to asymmetric B0↔B̄0 mixing and decay, we extract the CP-...

No. of bitstreams: 0 Previous issue date: 2006-12-06; We present a measurement of the top quark mass with the matrix element method in the lepton+jets final state. As the energy scale for calorimeter jets represents the dominant source of systematic uncertainty, the matrix element likelihood is extended by an additional parameter, which is defined as a glo...
