Abstract

The NA52 experiment at CERN has investigated lead-lead collisions at 158 A GeV/c and searched for long-lived strange quark matter droplets, so-called strangelets, with a unique signature of a high mass-to-charge ratio. This ratio was measured in a focusing spectrometer equipped with a time-of-flight system. A total of 3 × 10¹¹ Pb + Pb interactions at positive and 10 ¹³ at negative spectrometer polarities have been recorded. No strangelet has been observed, which sets experimental upper limits (90% CL) for the strangelet production at 3 × 10^-9 per interaction for positively charged and at 2 × 10^-10 per interaction for negatively charged strangelets.
