Pentaquark Searches at CDF

Abstract

Experimental results of a search for the Xi_(3/2)(1860) cascade pentaquark state in data collected with the CDF 2 Detector in Run II at the Tevatron are presented. No evidence for these states in the neutral Xi-pi+ and doubly charged Xi-pi- modes has been found. Preliminary upper limits on yields at 1862 MeV/c**2 relative to the well established resonance Xi*0(1530) are presented.
