Query: Measurement of the Decay Rate of Xi_c^0 --> pK^-K^-pi^+ Relative to
  Xi_c^0 --> Xi^-pi^+   Using the CLEOIII detector at CESR, we have measured the branching ratio of
the decay Xic0 to pK-K-pi+ relative to Xic0 to Xi- pi+. We find B(Xic0 to
pK-K-pi+)/B(Xic0 to Xi-pi+)= 0.35+/-$0.08(stat)+/-0.05(syst). In the resonant
substructure of this mode, we find evidence for Xi_c0 decays to p K*(890)K-,
and measure B(Xic0 to p K*(890) K^-).B(K*(890) to K-pi+) /B(Xic0 to
Xi-pi+)=0.14+/-0.04(stat)+/-0.02(syst) and B(Xic0 to pK-K-pi+)/B(Xic0 to
Xi-pi+)=0.21+/-0.05(stat)+/-0.03(syst) for the non-resonant Xic0 decays
pK-K-pi+ decays.
