Query: A partial wave analysis of the centrally produced pi0pi0 system in pp
  interactions at 450 GeV/c   A partial wave analysis of the centrally produced pi0pi0 channel has been
performed in pp collisions using an incident beam momentum of 450 GeV/c. An
unambiguous physical solution has been found. Evidence is found for the
f0(980), f0(1300) and f0(1500) in the the S-wave. and the f2(1270) is observed
dominantly in the D0-wave. In addition, there is evidence for a broad
enhancement in the D-wave below 1 GeV.
