ABSTRACT

We present the results of a search in $p{\bar p}$ collisions at
$\roots= 1.8$~TeV for anomalous production of events containing a
photon with large transverse energy and a lepton ($e$ or $\mu$) with
large transverse energy, using 86 pb$^{-1}$ of data collected at the
Collider Detector at Fermilab during the 1994-95 collider run at the
Fermilab Tevatron.  The presence of large missing transverse energy
($\mett$), additional photons, or additional leptons in these events
is also analyzed.  The results are consistent with standard model
expectations, with the possible exception of photon-lepton events with
large $\mett$, for which the probability of a statistical fluctuation
of the standard model expectation up to and above the observed level
is 0.7\%.
