Query: Recent results on anomalous J/psi suppression in Pb-Pb collisions at 158
  AGeV/c   We report our latest results on charmonium suppression as measured at the
CERN-SPS in Pb-Pb interactions at an incident beam momentum of 158 GeV/c per
nucleon. Preliminary results obtained from the most recent sample of data
collected in year 2000 under improved experimental conditions are compared with
published results. For the most peripheral Pb-Pb collisions, J/psi suppression
agrees with the normal absorption measured from interactions of lighter nuclei
while a steady increasing abnormal supression is observed with increasing
centrality.
