We present results of a search for strange quark matter (strangelets) in 11.5A GeV /c Au+Pb collisions from the 1994 and 1995 runs of experiment E864 at Brookhaven{close_quote}s Alternating Gradient Synchrotron. We observe no strangelet candidates and set a 90{percent} confidence level upper limit of approximately 3{times}10{sup {minus}8} per 10{percent} central interaction for the production of {vert_bar}Z{vert_bar}=1 and {vert_bar}Z{vert_bar}=2 strangelets over a large mass range and with metastable lifetimes of about 50ns or more. These results place constraints primarily on quark-gluon plasma based production models for strangelets. {copyright} {ital 1997} {ital The American Physical Society}
