We present results for various searches for signatures of standard and non-standard model Higgs boson decays conducted at the collider detectors CDF and D0 using (almost equal to)100 pb−1 of integrated luminosity each from the Tevatron collider Run 1 (1992-96) at (square root)s=1.8 TeV. No evidence for a Higgs boson decay is found and various limits are set.

This paper summarizes recent Higgs searches in p{anti p} collisions at √s = 1.8 TeV from the Tevatron using Run I data. Emphasis is given to a new result from the CDF collaboration in searching for neutral minimal SUSY Higgs bosons through the four jet reaction p{anti p} → b{anti b}[phi] → b{anti b}b{anti b}. Both the CDF and D0 experiments have also searched for standard model as well as other non-standard Higgs signatures in the mass region below ~ 140 GeV/c2 with no evidence of new physics.

We present the latest results on searches for the standard and beyond-the-standard model Higgs bosons in proton-antiproton collisions at (square root)s = 1.96 TeV by the CDF and D0 experiments at the Fermilab Tevatron. No significant excess is observed above the expected background, and the cross section limits for the Higgs bosons are calculated. It is noticed that the standard model Higgs boson in the mass range 163-166 GeV/c2 is excluded at the 95% C.L.

In this paper a summary of present CDF and D0/ results on supersymmetry and Higgs searches at Tevatron is presented. Analysis include results from a variety of signatures: missing E{sub T} and jets (or leptons and jets) for squark/gluino searches, trileptons and missing E{sub T} for gaugino searches and, for the first time, charmed-tagged jets and missing E{sub T} as a new signature for stop quark pair production. We show also results for various searches of standard and non-standard model Higgs bosons in hadron collisions. The seeked signature is Higgs associated production with a vector boson. Different channels involve jets and leptons from vector boson decays and b-tagged jets or photons from Higgs decays.

This paper presents an overview of recent experimental direct searches for Higgs-boson and beyond-the-standard-model (BSM) physics shown in the plenary session at the SUSY07 conference. The results reported correspond to an integrated luminosity of up to 2 fb−1 of Run II data from p{bar p} collisions collected by the CDF and D0 experiments at the Fermilab Tevatron Collider. Searches covered include: the standard model (SM) Higgs boson (including sensitivity projections), the minimal supersymmetric extension of the standard model (MSSM), charged Higgs bosons and extended Higgs models, supersymmetric decays that conserve R-parity, gauge-mediated supersymmetric breaking models, long-lived particles, leptoquarks, extra gauge bosons, extra dimensions, and finally signature-based searches. Given the excellent performance of the collider and the continued productivity of the experiments, the Tevatron physics potential looks very promising for discovery in the coming larger data sets. In particular, the Higgs boson could be observed if its mass is light or near 160 GeV.

With almost 0.5 fb{sup -1} of p{bar p}-collisions delivered in Tevatron Run II, both experiments CDF and D0 are reporting first results from a vast number of search analyses. This article summarizes the current status of Tevatron searches for Higgs bosons within the Standard Model and its extensions as well as direct searches for supersymmetric particles. Signatures for production of squarks, gluinos, charginos and neutralinos as predicted by gravity- and gauge-mediated SUSY breaking scenarios have been considered. No evidence for Higgs bosons or SUSY particles has been found so far. New limits are derived which significantly improve on existing limits.

We present the results of searches by the CDF and D{O} Collaborations for Higgs boson production in p{bar p} collisions at {radical}s = 1:96 TeV. The searches are performed in a range of production and decay channels predicted by the Standard Model and its minimal supersymmetric extension (MSSM) with data samples corresponding to 200-950 pb{sup 1}. In the absence of signal, the results are used to set upper limits on Higgs production cross sections times branching fractions.
