DOWNLOAD EBOOKThe Run II era at Fermilab began in March 2001. Many changes to the accelerator complex were made to support the Tevatron proton-antiproton collider operation with peak luminosities of 2-4 x 1032 cm−2 s−1 while delivering greater than 5 fb−1 of integrated luminosity before the LHC begins its physics program. This report describes the current status of Run II operations and the machine performances needed to achieve the goals.

DOWNLOAD EBOOKIn this dissertation we present a search for the associated production of charginos and neutralinos, the supersymmetric partners of the Standard Model bosons. We analyze a data sample representing 745 pb{sup -1} of integrated luminosity collected by the CDF experiment at the p{bar p} Tevatron collider. We compare the Standard Model predictions with the observed data selecting events with three leptons and missing transverse energy. Finding no excess, we combine the results of our search with similar analyses carried out at CDF and set an upper limit on the chargino mass in SUSY scenarios.

DOWNLOAD EBOOKThis Thesis describes the first measurement of, and constraints on, Higgs boson production in the vector boson fusion mode, where the Higgs decays to b quarks (the most common decay channel), at the LHC. The vector boson fusion mode, in which the Higgs is produced simultaneously with a pair of quark jets, provides an unparalleled opportunity to study the detailed properties of the Higgs, including the possibility of parity and CP violation, as well as its couplings and mass. It thus opens up this new field of study for precision investigation as the LHC increases in energy and intensity, leading the way to this new and exciting arena of precision Higgs research.

DOWNLOAD EBOOKThe 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.

DOWNLOAD EBOOKCompelling arguments suggest the presence of new physics at the electroweak scale, an energy regime accessible to the Fermilab Tevatron. Unfortunately, predictions for the form that new physics will take are all over the map. A quasi-model-independent search strategy for new physics (SLEUTH) was introduced in Tevatron Run I to allow a probe of high-pT hadron collider data. This dissertation prescribes the SLEUTH algorithm that will be used in Tevatron Run II. Improvements over the Run I algorithm are discussed, and an intuition is developed for SLEUTH'S performance by considering a number of beyond-the-standard-model examples. This dissertation defines a priori the SLEUTH algorithm, before its application to Tevatron Run II data, allowing an unbiased and rigorous a posteriori measure of the "interestingness" of any observed signal. This algorithm will also be used with small modifications at the Large Hadron Collider at CERN. In addition, a new detector simulation, TurboSim, was tested for physics analysis use for the first time.

DOWNLOAD EBOOKThe authors review the searches for supersymmetric particles achieved by the CDF and D0 collaborations at the p{bar p} Tevatron collider at FNAL, at (square root)s = 1.8 TeV and with a total integrated luminosity of 110 pb−1, per experiment. The prospects for the forthcoming run at (square root)s = 2 TeV and an integrated luminosity reaching ultimately at least 20 fb−1, are also discussed.
