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.
