PENTAQUARKS AND THE X(3872) RESULTS FROM CDf

摘要

We report results of the searches for pentaquark states in decays to pK_S~0, Ξ~- π~± and D~((*))p performed at CDF using 250 pb~(-1) sample of pp interactions at s~(1/2) of 1.96 TeV. No evidence for narrow resonances was found in either mode. In addition, we present measurements of properties of the recently discovered X(3872) particle.
