Using a small volume expansion the mass spectrum and deconfining temperature of SU(2) and SU(3) gauge theory are evaluated. Including non-perturbative features by restoring symmetries which were broken in perturbation theory we obtain results which are valid up to intermediate volumes. The mass spectrum obtained is in good agreement with Luscher's small volume expansion in the small-volume limit and with Monte Carlo Data in medium sized volumes. Using asymmetric volumes we are able to derive the deconfining temperature and find a reasonable agreement with Monte Carlo calculations. / Source: Dissertation Abstracts International, Volume: 51-01, Section: B, page: 0257. / Major Professor: Bernd A.

Supersymmetry (SUSY) has been known as a beautiful solution to the fine tuning problem of the Standard Model but so far there is no direct experimental evidence of its existence. However, the coming decade could be the decade of SUSY due to the ongoing project of the CERN Large Hadron Collider (LHC). Several SUSY signals for the LHC have been studied; the potential for a thorough SUSY search has been demonstrated. By looking at multi-jet plus $E\sb{T}$ events, $m\sb{\tilde g} \sim$ 1300 (2000) GeV can be explored if $m\sb{\tilde q} \gg m\sb{\tilde g}$ $(m\sb{\tilde q} \simeq m\sb{\tilde g});$ jet multiplicity will yield information on whether squark production makes a significant contribution; reconstructing hemisphere masses may yield a measure of $m\sb{\tilde g}$ to 15-25%. For the trilepton signal, a set of cuts was developed to isolate $\tilde\chi\sbsp{1}{\pm}\tilde\chi\sbsp{2}{0}$ events; as long as the spoiler modes (i.e. $\tilde\chi\sbsp{2}{0} \to \tilde\chi\sbsp{1}{0}Z$ and $\tilde\chi\sbsp{2}{0}$ $\to \tilde\chi\sbsp{1}{0}H\sb\ell$) are not open and the $\tilde\chi\sbsp{2}{0}\to\tilde\chi\sbsp{1}{0}\ell\bar\ell$ interference effect is not severe, most of the parameter space can be probed. A precise measurement of $m\sb{\tilde\chi\sbsp{2}{0}} \ - m\sb{\tilde\chi\sbsp{1}{0}}$ can be made. For the dilepton signal from slepton production, $m\sb{\tilde\ell\sb{R}} \sbsp{\sim}{<}$ 200-275 GeV ought to be explorable. Physics at the unification scale ($\sim$10$\sp{16}$ GeV) described in the supergravity (SUGRA) model can also be tested at the LHC. / Source: Dissertation Abstracts International, Volume: 56-08, Section: B, page: 4381. / Major Professor: Howard A.

A search for the pair production of supersymmetric particles using data from the DO detector at the Fermilab pp Tevatron collider, with center of mass energy $\sqrt{s}$ = 1.8 TeV, has yielded a null result. The search was performed looking for gluino and squark decays with a signature of multiple particle jets and high missing transverse energy. With a total luminosity of 7.5 pb$\sp{-1}$ of data, and with no signal events observed above expected Standard Model backgrounds, the existence of gluinos and squarks has been excluded with masses below 213 GeV/c$\sp2$ at the 95% confidence level for equal squark and gluino mass. / Source: Dissertation Abstracts International, Volume: 56-08, Section: B, page: 4382. / Major Professor: Horst Wahl. / Thesis (Ph.D.)--The Florida State University, 1995.
