   Both experiments measure the production of strange and
multistrange hyperons and antihyperons in relativistic heavy ion
collisions as a function of energy and centrality at the
CERN SPS heavy ion beam.


   WA97 took data during the years 1994-1996 in the hall West, NA57 in 1998-2001
in the hall Nord. Decision to stop data taking in NA57 experiment was done
07/02/2003.

   Secondary particles are detected in the limited kinematic window
( p_T > .5 GeV/c, central rapidity in CMS). The main part of
detector is a Silicon Pixel Telescope.

Activities of Prague group :

• Hardware responsibility during data taking at CERN

• Geometric and kinematic reconstruction of data in Prague

• Analysis

• Articles about WA97 and NA57 experiments in Czech press
