People : Physicists : P. Zavada (Team leader), P. Staroba Technician : J. Weichert Friend : K. Piska 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.
