Measurement of the decay rate of Xi(0)(c)-> pK(-)K(-)pi(+) relative to Xi(0)(c)->Xi(-)pi(+)

pK(-)K(-)pi(+) relative to Xi(c)(0)-->Xi(-)pi(+). We find B(Xi(c)(0)-->pK(-)K(-)pi(+))B(Xi(c)(0)-->Xi(-)pi(+))=0.35+/-0.06(stat)+/-0.03(syst). In the resonant substructure of this mode, we find evidence for Xi(c)(0) decays to pK(*)(892)K-0(-), and measure B(Xi(c)(0)-->pK(*)(892)K-0(-))xB(K-*(892)(0)-->K(-)pi(+))/B(Xi(c)(0)-->Xi(-)pi(+))=0.14+/-0.03(stat)+/-0.01(syst) and B(Xi(c)(0)-->pK(-)K(-)pi(+))/B(Xi(c)(0)-->Xi(-)pi(+))=0.21+/-0.04(stat)+/-0.02(syst) for the non-K-*(892)(0)Xi(c)(0)-->pK(-)K(-)pi(+) decays. -->

Popis: Using the CLEO III detector at CESR, we have measured the branching ratio of the decay Xi(c)(0)-->pK(-)K(-)pi(+) relative to Xi(c)(0)-->Xi(-)pi(+). We find B(Xi(c)(0)-->pK(-)K(-)pi(+))B(Xi(c)(0)-->Xi(-)pi(+))=0.35+/-0.06(stat)+/-0.03(syst). In the resonant substructure of this mode, we find evidence for Xi(c)(0) decays to pK(*)(892)K-0(-), and measure B(Xi(c)(0)-->pK(*)(892)K-0(-))xB(K-*(892)(0)-->K(-)pi(+))/B(Xi(c)(0)-->Xi(-)pi(+))=0.14+/-0.03(stat)+/-0.01(syst) and B(Xi(c)(0)-->pK(-)K(-)pi(+))/B(Xi(c)(0)-->Xi(-)pi(+))=0.21+/-0.04(stat)+/-0.02(syst) for the non-K-*(892)(0)Xi(c)(0)-->pK(-)K(-)pi(+) decays.
