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.

Searching for and potential discovery of Higgs boson(s) both within and beyond the standard model is perhaps the most visible physics goal of the current Fermilab Tevatron program. In this proceeding, recent results from both the CDF and D0 experiments based on analyses of datasets with integrated luminosities between 1.7 and 3.0 fb−1 are summarized. The combined Tevatron cross section upper limits on the production of a standard model Higgs boson are fast approaching the expected standard model values for a wide mass range. Particularly, the Tevatron has now excluded a standard model Higgs boson with a mass of 170 GeV at 95% C.L.

Although the standard model of particle physics (SM) is remarkably successful at describing the fundamental particles and their interactions, the mechanism for the breaking of elecroweak symmetry (EWSB) has yet to be confirmed. In the SM, the EWSB sector consists of four scalar fields represented by a single SU(2) complex doublet. Following EWSB, three of the fields are responsible for the generation of the W{sup {+-}} and Z masses, while the fourth is the neutral Higgs boson. At the present time, the Tevatron experiments have set 95% CL exclusion limits on the mass of the SM Higgs boson for the ranges 100 to 109 GeV and 158 to 175 GeV. In addition to these constraints on the SM Higgs boson, the Tevatron experiments have also set limits on neutral and charged Higgs bosons (H{sup {+-}}) in the context of several models beyond the SM. In this review, we discuss searches for charged Higgs bosons performed by the CDF and D0 collaborations at the Fermilab Tevatron in the mass range of 80 to 300 GeV.

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 results from the search for a standard model Higgs boson using data corresponding up to 10 fb−1 of proton-antiproton collision data produced by the Fermilab Tevatron at a center-of-mass energy of 1.96 TeV. The data were recorded by the CDF and D0 detectors between March 2001 and September of 2011. A broad excess is observed between 105

The CDF and D0 experiments at Fermilab's Tevatron have been actively searching for the Higgs bosons that appear in extensions of the minimal standard model. Here we present the results of searches for the neutral and charged Higgs bosons of the minimal supersymmetric standard model, as well as searches for doubly charged Higgs bosons that are predicted by other types of extensions. Up to 900 pb{sup -1} of Run 2 data have been analyzed and have provided no signs of Higgs boson production; these null results are used to set limits on Higgs production scenarios within the context of particular models.

The search for the Higgs boson is one of the main goals in High Energy Physics and one of the highest priorities at Run II of the Tevatron. There are many alternative Higgs boson models beyond the SM, including Supersymmetry (SUSY) and Fermiophobic Higgs bosons, which can actively be probed at the Tevatron, and in the absence of an excess constrained. The latest limits for several SUSY searches are presented in Section 2 and for the Fermiophobic Higgs boson searches in Section 3. More information on all these searches, along with the latest results, can be found on the CDF and D0 public results webpages. Results are presented for beyond the Standard Model Higgs boson searches using up to 4.2 fb−1 of data from Run II at the Tevatron. No significant excess is observed in any of the channels so 95% confidence level limits are presented.
