Collaborators,

        
        I am posting my Thesis (CDF Note  4582), completed in December 1997. 


    The title is:

    SEARCHES   FOR NEW   PHYSICS IN   DIPHOTON  EVENTS IN  PPBAR   COLLISIONS AT
                                SQRT(S)=1.8 TEV

    The abstract reads as follows:


    We have searched for anomalous  production of missing E$_{\rm T}$ ($\mett$),
jets,  leptons ($e, \mu,  \tau$),  $b$-quarks, or  additional  photons in events
containing    two   isolated,   central       \mbox{($|\eta|<1.0$)} photons with
\mbox{$\Et>12$~GeV}.      The   results  are    consistent  with  Standard Model
expectations, with the  possible exception of one  event that has in addition to
the two photons a central electron, a  high-E$_{\rm T}$ electromagnetic cluster,
and  large  $\mett$.  We  set  limits  using two   specific  SUSY  scenarios for
production of diphoton events with $\mett$.


                                           Thanks,

                                                Dave Toback
