  • Title: Status of Pentaquark Searches

  • Abstract:
    Recently there has been revival of interest in exotic baryon spectroscopy triggered by experimental evidence for pentaquarks containing u,d,s and c-quarks. I will report the results of the searches for pentaquark states decaying to proton K0s, Xi- pi-(+), D(0,-,*-) proton, J/psi proton, were performed with the upgraded CDF Run II detector running in pp= collisions at sqrt{s}=1.96 TeV. The search strategy was based on exploiting strong features of the CDF detector, such as excellent tracking capabilities, good PID system and unique displaced b-hadronic trigger. An overview of pentaquark searches performed by other experiments will be given.
