Abstract of "A Search for Chargino-Neutralino Production at the Fermilab
Tevatron Collider"

a Dissertation by Benn Tannenbaum


Abstract:


We have searched for evidence of supersymmetry with the Collider Detector at
Fermilab using trilepton events in $p \overline{p}$ collisions at $\sqrt{s}$ =
1.8~TeV. In the Minimal Supersymmetric Standard Model (MSSM), we expect
trilepton events from chargino-neutralino ($\chione \chitwo$) pair production,
with subsequent decay into leptons. In all possible combinations of electron
and muon channels, we observe no candidate events in 107 pb$^{-1}$ of data. We
present limits on chargino and neutralino production within the framework of a
supergravity inspired MSSM: $\sigma_{\chione\chitwo}\cdot
$BR(\chione\chitwo$\rightarrow 3\ell+X) < 0.34$~pb and M$_\chione > $ 81.5
\mgev\sp for $\tan\beta=2$, $\mu = -600$ \mgev\sp and M$_\squark=$ M$_\gluino$.
We also present limits on a SU(5)$\times$U(1) supergravity model and a 4 and
1/2 parameter Minimal SUGRA model.
