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.

As of July 2005, the Tevatron at Fermilab has delivered {approx} 1 fb{sup -1} of data to the CDF and D0 experiments. Each experiment has recorded more than 80% of the delivered luminosity. Results of searches for physics (non-SUSY and non-Higgs) beyond the Standard Model using 200 pb{sup -1} to 480 pb{sup -1} at D0 and CDF are presented.

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.

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.

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.

Theoretical frameworks beyond the standard model predict a rich Higgs sector with multiple charged and neutral Higgs bosons. Both the CDF II and D0 experiments at the Tevatron have analyzed 1 fb−1 of p{bar p} collisions at (square root)s = 1.96TeV in search of Higgs boson production. A complete suite of results on searches for neutral, charged, and fermiophobic Higgs bosons limit the allowed production rates and constrain extended models, including the minimal supersymmetric standard model.

The recent observation of the Higgs boson has been hailed as the scientific discovery of the century and led to the 2013 Nobel Prize in physics. This book describes the detailed science behind the decades-long search for this elusive particle at the Large Electron Positron Collider at CERN and at the Tevatron at Fermilab and its subsequent discovery and characterization at the Large Hadron Collider at CERN. Written by physicists who played leading roles in this epic search and discovery, this book is an authoritative and pedagogical exposition of the portrait of the Higgs boson that has emerged from a large number of experimental measurements. As the first of its kind, this book should be of interest to graduate students and researchers in particle physics.
