We report on a search for anomalous production of events with at
least two charged, isolated, like-sign leptons with p(t) > 11 GeV/c using a
107 pb-1 sample of 1.8 TeV p anti-p collisions collected by the CDF detector.
We define a signal region containing low background from Standard Model
processes. To avoid bias, we fix the final cuts before examining the event
yield in the signal region using control regions to test the Monte Carlo
predictions. We observe no events in the signal region, consistent with an
expectation of 0.63+0.84_-0.07 events. We present 95% confidence level
limits on new physics processes in both a signature-based context as well as
within a representative minimal supergravity (tan Beta = 3) model.
