Pentaquark Searches at CDF

Recently there has been revival of interest in exotic baryon spectroscopy triggered by experimental evidence for pentaquarks containing u, d, s and c-quarks. We report results of the searches for pentaquark states in decays to pKS0, Ξ−π± and D*−p performed at CDF detector using 220 pb−1 sample of pb¯ interactions at s of 1.96 TeV. No evidence for narrow resonances were found in either mode.
