چکیده

We present a search for the technicolor particles rho{T} and pi_{T} in the process pp-->rho{T}-->Wpi{T} at a center of mass energy of sqrt[s]=1.96 TeV. The search uses a data sample corresponding to approximately 1.9 fb{-1} of integrated luminosity accumulated by the CDF II detector at the Fermilab Tevatron. The event signature we consider is W-->lnu and pi{T}-->bb, bc or bu depending on the pi{T} charge. We select events with a single high-p{T} electron or muon, large missing transverse energy, and two jets. Jets corresponding to bottom quarks are identified with multiple b-tagging algorithms. The observed number of events and the invariant mass distributions are consistent with the standard model background expectations, and we exclude a region at 95% confidence level in the rho{T}-pi{T} mass plane. As a result, a large fraction of the region m(rho{T})=180-250 GeV/c{2} and m(pi{T})=95-145 GeV/c{2} is excluded.

Search for SM Higgs Boson Produced in Association with a Z or a W Boson in events with / ET and b-jets

We present a search for the Standard Model Higgs boson produced in association with a Z or a W boson, using data collected with the CDF II detector at the Tevatron accelerator. A scenario where the Z decays into neutrinos or charged leptons originating from the W-decay escape detection and the Higgs decays into a bb pair is considered. Therefore the expected signature is large missing transvers...

Non - Susy Exotic Particle Searches at the Tevatronjosh

Between 1992 and 1995, the CDF and DD collaborations collected data from p p collisions at p s = 1.8 TeV. Recently, several analyses of this data have been performed in search of evidence for various non-Supersymmetric exotic particles. As no evidence for the existence of these particles is observed, conndence level limits are established for exotic particle predictions from various theoretical...

Combined CDF and D 0 Upper Limits on Standard Model Higgs Boson Production with up to 8

We combine results from CDF and D0's direct searches for the standard model (SM) Higgs boson (H) produced in p¯ p collisions at the Fermilab Tevatron at √ s = 1.96 TeV. The results presented here include those channels which are most sensitive to Higgs bosons with mass between 130 and 200 GeV/c 2 , namely searches targeted at Higgs boson decays to W + W − , although acceptance for decays into τ...

Discovering New Interactions at Colliders

We summarize results of the 1996 Snowmass workshop on future prospects for discovering dynamical electroweak symmetry breaking, compositeness, and anomalous couplings of quarks at colliders. We present the mass reach of the Tevatron to a color singlet or octet technirho, and to a topgluon or topcolor Z from topcolor assisted technicolor. We explore the sensitivity of the Tevatron, LHC, NLC, and...
