Book Description
The Collider Detector at Fermilab collected approximately 200 pb -1 of Tevatron pp¯ collision data at s = 1.96 TeV between spring 2002 and fall 2003. We present results for searches for new physics in the dimuon final state using these data. The searches include heavy neutral particles predicted within extended gauge groups (various Z's), Technicolor (vector mesons), R-parity violating Supersymmetry (scalar neutrino), and warped extra dimensions (Randall-Sundrum gravitons). We present 95% Confidence Level (C.L.) upper limits on the production cross section times the branching ratio of new particles as a function of the dimuon invariant mass and place 95% C.L. lower mass bounds on the particles. Current limits exceed published limits of previous direct searches in the dimuon channel. We also pioneered search strategies and exploration of some models. Limit results from the electron and muon combined channels are also presented.

Book Description
The authors report on the first results from the CDF experiment on search for physics beyond the Standard Model using data from the upgraded TeVatron collider running p{bar p} collisions at (square root)s = 1960 GeV. These first results, although obtained with a total integrated luminosity lower than the total integrated luminosity collected during Run I, are already competitive if not better, due to the increase in the center of mass energy and the improved detector capability.

Book Description
A brief review of searches for physics beyond the Standard Model with photons using the CDF detector at the Tevatron is given here. These include searches for supersymmetry, extra dimensions, excited electrons and W/Z+[gamma] production, as well as anomalous photon production. Recent results from CDF Run II experiment are presented, but some results from Run I are also reviewed.

Book Description
Written by authors working at the forefront of research, this accessible treatment presents the current status of the field of collider-based particle physics at the highest energies available, as well as recent results and experimental techniques. It is clearly divided into three sections; The first covers the physics -- discussing the various aspects of the Standard Model as well as its extensions, explaining important experimental results and highlighting the expectations from the Large Hadron Collider (LHC). The second is dedicated to the involved technologies and detector concepts, and the third covers the important - but often neglected - topics of the organisation and financing of high-energy physics research. A useful resource for students and researchers from high-energy physics.

Book Description
We present results of recent searches for new physics using the CDF detector at the Fermilab Tevatron. Presented are searches for Higgs →??, as well as more general searches in?? + X where X is /E{sub T}, jets, charged leptons, b-quarks or extra photons. The CDF ee??/E{sub T} candidate event is discussed along with estimates of the expected rates in the Standard Model. Other searches for SUSY, Higgs and Technicolor look for particles which decay to vector bosons and b-quarks.

Book Description
The first precision measurements on CP violation in the B system are reported. Both the BELLE and the BABAR collaboration presented, among others, results for sin 2ß with much improved accuracy. Results from the Sudbury Neutrino Observatory, SNO, also deserve to be mentioned. The convincing evidence of solar neutrino oscillations had been presented by SNO prior to the conference; a full presentation was given at the conference. An incredibly precise measurement of the anomalous magnetic moment of the muon is reported, a fresh result from the Brookhaven National Laboratory. Apart from these distinct physics highlights, there are also the first results from the new Tevatron run and from the relativistic heavy ion collider RHIC. Theorists write of our ever better understanding of the Standard Model and of what might lie beyond. Risky as it is to highlight only a couple of exciting subjects, it is merely meantto whet the appetite for further reading.

Book Description
The search for physics beyond the Standard Model is one of the primary motivations of the Run II at the Tevatron. The CDF collaboration has been very active in this field by searching in a variety of final states for signals of new physics processes. The observation of no significant deviation from the Standard Model has led to limits on the cross-sections of the considered processes, which, in turn, have been used to constrain several models that predict such new physics scenarios.
