Book Description
We present the results of the searches for new phenomena in pp collisions at √s=1.8 TeV with the CDF detector using the full data sample of 110 pb−1 collected between 1992 and 1995. We have searched for new physics in events with two photons, testing some of the hypotheses proposed to explain the appearance of the CDF ee[gamma][gamma] E{sub T} event. New results on the search for a heavy neutral scalar object, charged Higgs bosons (H{sup {+-}}) and the scalar top quark are presented. Finally we summarize the CDF results on the search for third generation leptoquarks.

Book Description
The authors report on recent results from the Collider Detector at Fermilab (CDF) experiment, which is accumulating data from proton-antiproton collisions with {radical}s = 1.96 TeV at Run II of the Fermilab Tevatron. The new phenomena being explored include Higgs, Supersymmetry, and large extra dimensions. They also present the latest results of searches for heavy objects, which would indicate physics beyond the Standard Model.

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
'Dorigo provides an engaging and insightful perspective on the pursuit of physics discoveries at CDF … Dorigo’s book is thus almost certainly going to be an important source for anyone interested in the history of CDF … It is a personal yet highly informative story of discovery and almost-discovery from the perspective of someone who saw the events firsthand.'Physics TodayFrom the mid-1980s, an international collaboration of 600 physicists embarked on the investigation of subnuclear physics at the high-energy frontier. As well as discovering the top quark, the heaviest elementary particle ever observed, the physicists analyzed their data to seek signals of new physics which could revolutionize our understanding of nature.Anomaly! tells the story of that quest, and focuses specifically on the finding of several unexplained effects which were unearthed in the process. These anomalies proved highly controversial within the large team: to some collaborators they called for immediate publication, while to others their divulgation threatened to jeopardize the reputation of the experiment.Written in a confidential, narrative style, this book looks at the sociology of a large scientific collaboration, providing insight in the relationships between top physicists at the turn of the millennium. The stories offer an insider's view of the life cycle of the 'failed' discoveries that unavoidably accompany even the greatest endeavors in modern particle physics.

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
One of the fundamental roles of a general purpose detector exploring, by means of increasing luminosity, higher and higher mass reach, is to search for new particles and exotic phenomena. This is a continuing effort for the CDF collaboration, and will report on several searches using about 20 pb−1 from the 1992/93 run labelled {open_quotes}run 1a{close_quotes} and (approximately)50 of the 90 pb−1 so far from the current {open_quotes}run 1b.{close_quotes} These are mostly preliminary analyses, typically using a total of 70 pb−1. Our limits on SUSY using missing E{sub T} with jets as well as three leptons are discussed elsewhere; results from the D0 collaboration are similar. I will discuss searches for additional vector bosons Z(prime) and W(prime), second generation scalar leptoquarks, as well as a broad search for objects decaying into jet pairs, including b-tagged jet pairs. I will also describe two events which do not fit in comfortably with either the standard model or a phenomenologically motivated search.

Book Description
This book addresses one of the most intriguing mysteries of our universe: the nature of dark matter. The results presented here mark a significant and substantial contribution to the search for new physics, in particular for new particles that couple to dark matter. The first analysis presented is a search for heavy new particles that decay into pairs of hadronic jets (dijets). This pioneering analysis explores unprecedented dijet invariant masses, reaching nearly 7 TeV, and sets constraints on several important new physics models. The two subsequent analyses focus on the difficult low dijet mass region, down to 200 GeV, and employ a novel technique to efficiently gather low-mass dijet events. The results of these analyses transcend the long-standing constraints on dark matter mediator particles set by several existing experiments.

Book Description
The 1997 International Europhysics Conference on High Energy Physics was held at the campus of the Hebrew University of Jerusalem and at the Jerusalem Renaissance Hotel, from August 19th to August 25th, 1997. This was the first time that the European Physical Society had its High Energy Physics Conference outside the boundary of Europe. A total of 550 physicists participated in the conference with a total of 250 presentations in the parallel sessions and 26 presentations in the plenary sessions. The Board of the of the High Energy and Particle Physics division (HEPP) of the EPS acted as the Scientific Organizing Committee. The Board acknowl edges the help of the International Advisory Committee as well as that of the Local Organizing Committee. The conference was co-organized by the Hebrew University of Jerusalem and by the Weizmann Institute of Science, with important help by physi cists from the Israeli Institute of Technology (Technion) and the Tel Aviv University.
