“…They have refined particle identification techniques and adopted innovative analysis methods, resulting in precise measurements of the top quark mass and the tt production cross section. There exist several excellent reviews 5 of the work that led to the discovery and the work done shortly thereafter. Although we shall touch upon some of the highlights of that exciting time, the focus of this review is the current status of top quark physics resulting from the recent measurements from the Tevatron experiments.…”

The discovery of the top quark in 1995, by the CDF and DØ collaborations at the Fermilab Tevatron, marked the dawn of a new era in particle physics. Since then, enormous efforts have been made to study the properties of this remarkable particle, especially its mass and production cross section. In this article, we review the status of top quark physics as studied by the two collaborations using the pp collider data at √ s = 1.8 TeV. The combined measurement of the top quark mass, m t = 173.8±5.0 GeV/c 2 , makes it known to a fractional precision better than any other quark mass. The production cross sections are measured as σ tt = 7.6 +1.8 −1.5 pb by CDF and σ tt = 5.5± 1.8 pb by DØ. Further investigations of tt decays and future prospects are briefly discussed.

“…Since the discovery of the top quark in 1995 (7,8,14), the searches for the Higgs boson and for new physics have taken center-stage. The luminosity upgrades of the Fermilab Tevatron (15) in the past decade have produced unprecedented amounts of proton-antiproton collision data at the center of mass energy ( s ) of 1.96 TeV.…”

"That is positively the dopiest idea I have heard." -Richard Feynman, when he signed on to work on the Connection Machine, at the Thinking Machines Corporation, in the summer of 1983. Key WordsMultivariate methods, optimal analysis, neural networks, Bayesian inference, Tevatron, Large Hadron Collider (LHC) AbstractEach generation of high energy physics experiments is grander in scale than the previousmore powerful, more complex and more demanding in terms of data handling and analysis.The spectacular performance of the Tevatron and the beginning of operations of the Large Hadron Collider have placed us at the threshold of a new era in particle physics. The discovery of the Higgs boson or another agent of electroweak symmetry breaking and evidence of new physics may be just around the corner. The greatest challenge in these pursuits is to extract the extremely rare signals, if any, from huge backgrounds that arise from known physics processes. The use of advanced analysis techniques is crucial in achieving this goal. In this review, I discuss the concepts of optimal analysis, some important advanced analysis methods and a few examples. The judicious use of these advanced methods should enable new discoveries and produce results with better precision, robustness and clarity.

The top quark is the heaviest elementary particle observed to date. Its large mass of about 173 GeV/c 2 makes the top quark act differently than other elementary fermions, as it decays before it hadronises, passing its spin information on to its decay products. In addition, the top quark plays an important role in higher-order loop corrections to standard model processes, which makes the top quark mass a crucial parameter for precision tests of the electroweak theory. The top quark is also a powerful probe for new phenomena beyond the standard model. During the time of discovery at the Tevatron in 1995 only a few properties of the top quark could be measured. In recent years, since the start of Tevatron Run II, the field of top-quark physics has changed and entered a precision era. This report summarises the latest measurements and studies of top-quark properties and gives prospects for future measurements at the Large Hadron Collider (LHC).
