Abstract

The NA52 experiment searches for long-lived massive strange quark matter particles, so-called ${s t r a n g e l e t s, p r o d u c e d i n P b - P b c o l l i s i o n s a t a b e a m m o m e n t u m o f p_{lab} = 158 A GeV / c . U p p e r l i m i t s f o r t h e p r o d u c t i o n o f s t r a n g e l e t s a t z e r o d e g r e e p r o d u c t i o n a n g l e c o v e r i n g a m a s s t o c h a r g e r a t i o u p t o 120 GeV / c}^{2}$ and lifetimes $t_{lab} ≳ 1.2$ μs are given. The data presented here were taken during the 1994 lead beam running period at CERN.
