Abstract
We present recent results of the NA52 experiment on the strangelet sea rch and on particle, antiparticle, light nuclei and antinuclei product ion in minimum bias Pb+Pb collisions at 158 A GeV and zero production angle. Upper limits for the production of strangelets are given and on e candidate found using less stringent lifetime cuts is discussed. The rapidity dependence of K+(K-), p((p) over bar), d((d) over bar), t an d He-3(<(He-3)over bar>) as well as first results on He-4, Li-6 and Be -7 at forward rapidities are presented. First results on the centralit y dependence of the (p) over bar/p ratio are reported. Within the fram ework of a thermodynamical and a coalescence model, the temperature, t he baryon-and strangeness-chemical potentials and the radius of the pa rticle source at midrapidity have been estimated.
