Resumen

We present recent results of the NA52 experiment on the strangelet search and on particle, antiparticle, light nuclei and antinuclei production in minimum bias Pb+Pb collisions at 158 A GeV and zero production angle. Upper limits for the production of strangelets are given and one candidate found using less stringent lifetime cuts is discussed. The rapidity dependence of K+(K-), p(p̄), d(d), t and 3He(3He) as well as first results on 4He, 6Li and 7Be at forward rapidities are presented. First results on the centrality dependence of the p̄/p ratio are reported. Within the framework of a thermodynamical and a coalescence model, the temperature, the baryon- and strangeness-chemical potentials and the radius of the particle source at midrapidity have been estimated.
