Descripción
Sumario:Besides the dedicated search for strangelets NA52 measures light (anti)particle and (anti)nucleus production over a wide range of rapidity. Compared to previous runs the statistics has been increased in the 1998 run by more than one order of magnitude for negatively charged objects at different spectrometer rigidities. At a rigidity of -20 GeV/c we measured 10/sup 6/ p, 10/sup 3/ d and one /sup 3/He without any centrality requirements. These preliminary results together with previous measurements near central rapidity are discussed in the framework of a thermodynamical and a coalescence model. (18 refs).
