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.

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.

Recent results from searches for the SM and SUSY Higgs bosons in Run 1 at the Tevatron have been shown. The sensitivity of the present SM Higgs searches at the Tevatron is limited by statistics leading to a reach in p[bar p][r-arrow] VH production more than an order of magnitude higher than the SM prediction. The search for the neutral SUSY Higgs via p[bar p][r-arrow] b[bar b][psi][r-arrow] b[bar b]b[bar b] excludes regions in the tan[beta] vs M[sub A] space which extend significantly those previously probed by LEP. They have presented results from studies of the discovery and sensitivity reach for the Higgs bosons in Run 2. Combining all search channels and the data from both experiments a SM Higgs can be excluded at 95% CL over the full mass range M[sub H]

In Run 2 at the Tevatron, the upgraded CDF and D0 experiments will have greatly improved sensitivity in the search for the Higgs bosons of the Standard Model and minimal supersymmetry. In the past year the Higgs Working Group of the Tevatron Run 2 SUSY/Higgs Workshop has estimated the discovery and exclusion reach for the Higgs, combining all possible search channels and utilizing all the upgraded features of both detectors. The results give strong motivation to continue the next run of the Tevatron into Run 3, with an eventual goal of up to 20 fb-1 or more delivered per experiment.

The D0 and CDF experiments at the Tevatron have sought the Higgs boson in data collected till 1996, and have set limits to its existence. After a major upgrade of both detectors and substantial improvements of the acceleration complex, the two experiments have restarted collecting physics quality data in early 2002. It is expected that a Standard Model Higgs boson with mass lower than 180 GeV will be either discovered or ruled out with five years of running.
