First look at NA52 data on PbPb interactions at 158 GeV/c per nucleon

Abstract We have searched for strange matter particles, so-called strangelets , in PbPb interactions at p lab = 157.7 GeV/ c per nucleon. The NA52 apparatus is also ideally suited to measure production yields and rapidity distributions of π ± , K ± , p, p , d, d , … near 0° production angle. Some preliminary results are shown.
