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.
