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]

This book presents topics of major interest to the high energy physics community, as well as recent research results.

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 present upgrades of the CDF and DO detectors as well as of the Fermilab Tevatron have dramatically improved their sensitivity for Standard Model and minimal supersymmetry Higgs bosons searches in Run II. This paper reviews the recent estimates of this sensitivity in terms of Higgs discovery and exclusion reach based on a total expected Run II Tevatron luminosity of 15 fb−1 delivered to each experiment.

High Energy Physics 99 contains the 18 invited plenary presentations and 250 contributions to parallel sessions presented at the International Europhysics Conference on High Energy Physics. The book provides a comprehensive survey of the latest developments in high energy physics. Topics discussed include hard high energy, structure functions, soft interactions, heavy flavor, the standard model, hadron spectroscopy, neutrino masses, particle astrophysics, field theory, and detector development.

This important book covers topics that are of major interest to the high energy physics community, including the most recent results from flavour factories, dark matter and neutrino physics. In addition, it considers future high energy machines.

The Standard Model of particle physics is extremely successful in describing nature. It is, however, incomplete in one major way: the masses of gauge bosons and fermions enter the Standard Model through the Higgs mechanism. That is completely satisfactory technically, but it is not understood physically. We do not yet know what nature really does to give mass to particles. Understanding Higgs physics is necessary in order to complete the Standard Model, and to learn how to extend it and improve its foundations.This book is a collection of current work and thinking about these questions by active workers. It speculates about what form the answers will take, as well as updates and extends previous books and reviews. Some chapters emphasize theoretical questions, some focus on connections with other areas of physics, and some discuss how we can get data to uncover nature's solution. This second edition adds information and insights from the last five years, including the recent indirect but statistically significant evidence for the existence of a Higgs boson from precision measurements. It contains contributions from Blondel, Quiros, Haber, Pokorski, Dawson, Janot, Mrenna, Gunion, Ibanez, Ross, Bigi, Carena, Wagner, Georgi, Chanowitz, Yuan, Hill, and others.
