“…The underlying calculations needed to demonstrate the existence of the initial anomaly pole vertices we require can now be found in [21]. In calculations carried out after [22] was published, we showed explicitly how, in the scattering of electroweak vector bosons, effective vertices containing a triangle diagram are generated by the contraction of larger loop diagrams, in the channel with pion exchange quantum numbers.…”

“…In the remainder of this section, and the following sections, we will go far beyond the explicit calculations of [21,22]. We will introduce effective vertices for which the underlying (in general, multi-Regge) calculations have not, as yet, been carried out but whose existence is a natural extrapolation of the vertices that we have already discussed.…”

“…Conversely, since W's and Z's have explicit perturbative couplings, this amplitude also has a perturbative Reggeon diagram description. Most importantly for our program, because of the presence of elementary left-handed couplings, the perturbative Reggeon vertices of the external W and Z states contain [21] anomalies that can give (with the cutoff manipulation that we discuss below) the infrared divergences that we are looking for. We want, of course, to add the vector boson sector of the standard model to QCD S in order to study the sextet Higgs mechanism.…”

“…The presence of massive gluons in CSQCD S produces [21][22][23] triangle diagram anomalies in the effective vertices of Reggeon diagrams. The contribution of the anomalies is (not surprisingly) strongly dependent on ultraviolet and infrared cutoffs and so different ''solutions'' of the theory can be obtained, depending on how such cutoffs are handled.…”

Electroweak symmetry breaking may be a consequence of color sextet quark chiral symmetry breaking. A special solution of QCD is involved, with a high-energy S-Matrix that can be constructed ''semiperturbatively'' via the chiral anomaly and Reggeon diagrams. An infrared fixed point and color superconductivity are crucial components of the construction. Infinite-momentum physical states contain both quarks and a universal ''anomalous wee gluon'' component, and the spectrum is more limited than is required by confinement and chiral symmetry breaking. The Pomeron is approximately a Regge pole and the Critical Pomeron describes asymptotic cross sections. The strong coupling of the Pomeron to the electroweak sector could produce large x and Q 2 events at HERA, and vector boson pairs at Fermilab. Further evidence for the sextet sector at Fermilab would be a large E T jet excess, due in part to the nonevolution of s , and other phenomena related to the possibility that top quark production is due to the 6 . The sextet proton and neutron are the only new baryonic states. Sextet states dominate high-energy hadronic cross sections and stable sextet neutrons could produce both dark matter and ultrahigh energy cosmic rays. The cosmic ray spectrum knee suggests the effective sextet threshold is between Fermilab and LHC energies, with large cross-section effects expected at the LHC. Jet and vector boson cross sections will be very much larger than expected, and sextet baryons should also be produced. Double Pomeron produced states could provide definitive evidence for the existence of the sextet sector in the initial low luminosity running.

We search for pair production of the supersymmetric partner of the top quark, the stop quarkt 1 , decaying to a b-quark and a charginoχ ± 1 with a subsequentχ ± 1 decay into a neutralinoχ 0 1 , lepton , and neutrino ν. Using 2.7 fb −1 of √ s = 1.96 TeV pp collision data collected by the CDF II experiment, we reconstruct the mass of candidate stop events and fit the observed mass spectrum to a combination of standard model processes and stop signal. No evidence oft 1t1 production is found, therefore we set 95% C.L. limits on the masses of the stop and the neutralino for several values of the chargino mass and the branching ratio B χ ± 1 →χ 0 1 ± ν. 0.1. ACKNOWLEDGMENTS vi I am also thankful to all of my friends who have understood when I couldn't spend time with them, or attend their parties because of school. I am especially thankful to my good friends and rock climbing partners David Cherney and Lisa Hardy. The many trips rock climbing with these two helped me to remain sane the first two years of grad school. Starting from community college, David was perhaps the greatest influence in shaping my philosophy of and approach towards science; Lisa not only showed me how impressive the human intellect can be, but also at one point physically forced me to staying in grad school, when I otherwise wouldn't have. I am most thankful to my family. My parents have selflessly sacrificed so much, and worked so hard to provide my sibling and I with the best opportunities they could. They unknowingly conditioned me to pursue physics when I was young, encouraged me through college, and were always there for me in grad school, even though I don't think we knew or understood where it would go or what it could be useful for. For my families unconditional love, I will always be grateful. 0.2. INTRODUCTION vii 0.2. Introduction The research in this thesis was performed from August 2006 though May 2009, by Andrew Ivanov, Robin Erbacher and the author. The results represent the effort of a much larger group of people however. The accelerator division at Fermilab who run the Tevatron to give the D0 and CDF experiments their data. The people at CDF who built the detector, who run the online system to collect the data, who perform offline calibrations, data handling, computing support, software creation, and much more. This research also benefited from the techniques and tools pioneered by the researchers before us, which made this this analysis possible. Additionally, many people at CDF contributed to this analysis by helping to review it's integrity, as well as suggest improvements.
