摘要：

The NA52 experiment searches for long-lived massive strange quark matter particles, so-called strangelets, produced in Pb-Pb collisions at a beam momentum of p(lab) = 158 A GeV/c. Upper limits for the production of strangelets at zero degree production angle covering a mass to charge ratio up to 120 GeV/c(2) and lifetimes t(lab) greater than or similar to 1.2 mu s are given. The data presented here were taken during the 1994 lead beam running period at CERN.
